FIELD OF THE DISCLOSURE

The present disclosure is directed to methods for treating inflammatory bowel diseases, such as Crohn's disease and ulcerative colitis, and in particular, to methods for inducing clinical remission and endoscopic improvement of Crohn's disease or a clinical remission and endoscopic improvement of ulcerative colitis, using a JAK1 inhibitor. In certain embodiments, the patient is administered an induction dose of the JAK1 inhibitor to induce clinical remission and/or endoscopic improvement of the Crohn's disease or a clinical remission of ulcerative colitis, followed by administration of at least one maintenance dose of the JAK1 inhibitor thereafter.

BACKGROUND OF THE DISCLOSURE

Inflammatory bowel disease (IBD) involves chronic inflammation of a patient's digestive tract. IBD includes both Crohn's disease and ulcerative colitis. The exact cause of IBD is not known. The IBD can be idiopathic IBD.

Crohn's Disease (CD) encompasses a spectrum of clinical and pathological processes manifested by focal asymmetric, transmural, and occasionally granulomatous inflammation that can affect any segment of the gastrointestinal tract (Lichtenstein G R, Hanauer S B, Sandborn W J; Practice Parameters Committee of American College of Gastroenterology, Management of Crohn's disease in adults, Am J Gastroenterol. 2009; 104(2):465-83). The disease can affect persons of any age, and its onset is most common in the second and third decades. Females are affected slightly more than males, and the risk for disease is higher in some ethnic groups (Loftus E V Jr., “Clinical epidemiology of inflammatory bowel disease: incidence, prevalence, and environmental influences,” Gastroenterology, 2004; 126(6):1504-17; Probert C S, Jayanthi V, Rampton D S, et al., “Epidemiology of inflammatory bowel disease in different ethnic and religious groups: limitations and aetiological clues,” Int. J Colorectal Dis., 1996; 11(1):25-28). In North America, the incidence of CD is estimated to be 3.1 to 14.6 cases per 100,000 persons. Prevalence rates range from 26 to 99 cases per 100,000 persons. In Europe, CD has an incidence of 0.7 to 9.8 cases per 100,000 persons and a prevalence of 8.3 to 214 cases per 100,000 persons (Loftus E V Jr. Clinical epidemiology of inflammatory bowel disease: incidence, prevalence, and environmental influences. Gastroenterology. 2004; 126(6):1504-17).

CD has been characterized by significant morbidity including abdominal pain, diarrhea, weight loss/malnutrition, fatigue and a progressive nature that leads to complications such as fistulas, strictures and abscesses. In a population based study from southeastern Norway, a substantial number of patients demonstrated a stricturing or penetrating phenotype at 10 years after diagnosis (Solberg I C, Vatn M H, Hoie O, et al; IBSEN Study Group. Clinical course in Crohn's disease: results of a Norwegian population-based ten-year follow-up study. Clin Gastroenterol Heptaol. 2007; 5(12):1430-8). Moreover, approximately 80% of patients diagnosed with CD will require at least 1 surgery related to the disease at some point in time (Munkholm P, Langholz E, Davidsen M, et al. Intestinal cancer risk and mortality in patients with Crohn's disease. Gastroenterology. 1993:105(6):1716-23).

Ulcerative colitis (UC) is one of the two primary forms of idiopathic inflammatory bowel disease (IBD). It is postulated that UC is caused by unregulated and exaggerated local immune response to environmental triggers in genetically susceptible individuals (Hanauer S B. Update on the etiology, pathogenesis and diagnosis of ulcerative colitis. Nat Clin Pract Gastroenterol Hepatol. 2004; 1(1):26-31). UC is a chronic, relapsing inflammatory disease of the large intestine characterized by inflammation and ulceration of mainly the mucosal and occasionally submucosal intestinal layers. The highest annual incidence of UC was 24.3 per 100,000 person-years in Europe, 6.3 per 100,000 person-years in Asia and the Middle East, and 19.2 per 100,000 person-years in North America, with a prevalence of 505 cases per 100,000 persons in Europe and 249 cases per 100,000 persons in North America. (Molodecky N A, Soon I S, Rabi D M, et al. Increasing incidence and prevalence of the inflammatory bowel diseases with time, based on systematic review. Gastroenterology. 2012:142(1):46-54). There is increasing incidence and prevalence of the inflammatory bowel diseases with time, based on systematic review. (Gastroenterology. 2012; 142(1):46-54.e42; quiz e30.) The burden of UC on the healthcare system is profound, accounting for nearly 500,000 physician visits and more than 46,000 hospitalizations per year in the United States (US) alone. (Sandler R S, Everhart J E, Donowitz M, et al., Gastroenterology, 2002; 122(5):1500-11).

The hallmark clinical symptoms of UC include bloody diarrhea associated with rectal urgency and tenesmus. The clinical course is marked by exacerbation and remission. The diagnosis of UC is suspected on clinical grounds and supported by diagnostic testing, and elimination of infectious causes. (Dignass A, Eliakim R, Magro F, et al. Second European evidence-based consensus on the diagnosis and management of ulcerative colitis part 1: definitions and diagnosis. J Crohn's Colitis. 2012; 6(10):965-90)

The most severe intestinal manifestations of UC are toxic megacolon and perforation. Extraintestinal complications include arthritis (peripheral or axial involvement), dermatological conditions (erythema nodosum, aphthous stomatitis, and pyoderma gangrenosum), inflammation of the eye (uveitis), and liver dysfunction (primary sclerosing cholangitis). Patients with UC are at an increased risk for colon cancer, and the risk increases with the duration of disease as well as extent of colon affected by the disease. (Rutter M, Saunders B, Wilkinson K, et al. Severity of inflammation is a risk factor for colorectal neoplasia in ulcerative colitis. (Gastroenterology, 2004; 126(2):451-9).

The aim of medical treatment in UC is to control inflammation and reduce symptoms. Available pharmaceutical therapies are limited, do not always completely abate the inflammatory process, and may have significant adverse effects. Therapies for mild to moderate active UC include 5-aminosalicylic acid derivatives and immunosuppressants.

Corticosteroids are used in patients with more severe UC symptoms but are not useful for longer term therapy. (Truelove S C, Witts L J. Cortisone and corticotrophin in ulcerative colitis. Br Med 1959; 1(5119):387-94). The frequency and severity of corticosteroid toxicities are significant, including infections, emotional and psychiatric disturbances, skin injury, and metabolic bone disease. Corticosteroids are not effective for the maintenance of remission and the UC practice guidelines from the American College of Gastroenterology recommend against chronic steroid treatment. (Kornbluth A, Sachar D B; Practice Parameters Committee of the American College of Gastroenterology. Ulcerative colitis practice guidelines in adults: American College of Gastroenterology, Practice Parameters Committee. Am J Gastroenterol. 2010; 105(3):501-23; quiz 524). Patients with moderate to severe symptoms may derive some benefits from immunosuppressant agents (azathioprine [AZA], 6-mercaptopurine [6-MP], or methotrexate [MTX]); however, the use of these agents is limited as induction treatment due to a slow onset of action (3 to 6 months) and as maintenance therapy due to adverse events (AEs), including bone marrow suppression, infections, hepatotoxicity, pancreatitis, and malignancies. (Kornbluth A, Sachar D B; Practice Parameters Committee of the American College of Gastroenterology. Ulcerative colitis practice guidelines in adults: American College of Gastroenterology, Practice Parameters Committee. Am J Gastroenterol., 2010; 105(3):501-23; quiz 524; Beaugerie L, Brousse N, Bouvier A M, et al. Lymphoproliferative disorders in patients receiving thiopurines for inflammatory bowel disease: a prospective observational cohort study. Lancet. 2009; 374(9701):1617-25). Despite these therapies, approximately 15% of ulcerative colitis patients experience a severe clinical course, and 30% of these patients require removal of the colon/rectum, to eliminate the source of the inflammatory process, although accompanied by significant morbidity (Aratari A, Papi C, Clemente V, et al. Colectomy rate in acute severe ulcerative colitis in the infliximab era. Dig Liver Dis. 2008; 40(10):821-6; Turner D, Walsh C M, Steinhart A H, et al. Response to corticosteroids in severe ulcerative colitis: a systematic review of the literature and a meta-regression. Clin Gastroenterol Hepatol. 2007; 5(1):103-10).

Biological agents targeting specific immunological pathways have been evaluated for their therapeutic effect in treating patients with UC. Anti-tumor necrosis factor (TNF) agents were the first biologics to be used for IBD. Infliximab, adalimumab, and golimumab are successfully being used for the treatment of UC. Recently, vedolizumab, an anti-adhesion therapy, has been approved for the treatment of UC by the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA), and clinical development is ongoing in Japan.

Anti-TNF therapies are an effective treatment for patients who are steroid refractory or steroid dependent, who had inadequate response to a thiopurine, or who are intolerant to these medications. Potential risks with anti-TNF therapies include infusion or injection site reactions, serious infections, lymphoma, heart failure, lupus-like syndromes, and demyelinating conditions (Sandborn W J. State-of-the-art: immunosuppression and biologic therapy. Dig Dis. 2010; 28(3):536-42). Despite the beneficial results achieved with the available biologic agents, only 17% to 45% of patients who receive them are able to achieve clinical remission. (Rutgeerts P, Sandborn W, Feagan B, et al., Infliximab for induction and maintenance therapy for ulcerative colitis. N Engl J Med. 2005, 353(23):2462-76; Sandborn W J, van Assche G, Reinisch W, et al. Adalimumab induces and maintains clinical remission in patients with moderate-to-severe ulcerative colitis. Gastroenterology, 2012, 142(2):257-65; Feagan B, Greenberg G, Wild G, et al., Treatment of ulcerative colitis with a humanized antibody to the alpha4beta7 integrin, N. Engl. J. Med. 2005, 352(24):2499-507; Sandborn W, Feagan B, Marano C, et al. Subcutaneous golimumab induces clinical response and remission in patients with moderate-to-severe ulcerative colitis, Gastroenterology, 2014, 146(1): 85-95; quiz e14-5), Thus, there remains a clear medical need for additional therapeutic options in UC for patients with inadequate response to or intolerance to conventional therapies and biologic therapies

Given that no known medical or surgical cure currently exists for CD, the therapeutic strategy is to reduce symptoms, improve quality of life, reduce endoscopic evidence of inflammation, and minimize short- and long term toxicity and complications (Lichtenstein G R, Hanauer S B, Sandborn W J; Practice Parameters Committee of American College of Gastroenterology, Management of Crohn's disease in adults, Am J Gastroenterol., 2009, 104(2):465-83). Currently, patients with moderate to severe disease are usually treated with conventional pharmacologic interventions, which include corticosteroids and immunosuppressant agents such as azathioprine, 6-mercaptopurine, or methotrexate (MTX) (Lichtenstein G R, Hanauer S B, Sandborn W J, Practice Parameters Committee of American College of Gastroenterology, Management of Crohn's disease in adults, Am J Gastroenterol, 2009, 104(2):465-83; Dignass A, Van Assche G, Lindsay J O, et al., European Crohn's and Colitis Oganisation (ECCO), The second European evidence-based Consensus on the diagnosis and management of Crohn's disease: current management, J Crohn's Colitis, 2010, 4(1):28-62, Erratum in: J Crohn's Colitis, 2010, 4(3):353).

The potential risks from long term use of corticosteroids are well-known. Adverse events (AEs) associated with short-term use of corticosteroids include acne, moon face, edema, skin striae, glucose intolerance, and sleep/mood disturbances, while potential AEs observed with longer term use (usually 12 weeks or longer but sometimes shorter durations) include posterior subcapsular cataracts, osteoporosis, osteonecrosis of the femoral head, myopathy, and susceptibility to infection (Irving P M, Gearry R B, Sparrow M P, et al., Review article: appropriate use of corticosteroids in Crohn's disease, Aliment Pharmacol Ther., 2007, 26(3):313-29; Rutgeerts P J, Review article: the limitations of corticosteroid therapy in Crohn's disease, Aliment Pharmacol Ther., 2001, 15(10):1515-25). The safety risks for azathioprine and 6-mercaptopurine include pancreatitis, bone marrow depression, infectious complications, and malignant neoplasms (Sandborn, W J, State-of-the-art: immunosuppression and biologic therapy, Dig Dis., 2010, 28(3):536-42). MTX may be associated with nausea, bone marrow depression and liver and pulmonary toxicity (Siegel, et al., Review article: Practical Management of Inflammatory Bowel Disease Patients Taking Immunosuppressants, Aliment Pharmacol Ther., 2005, 22:1-16). Patients who do not respond to conventional therapies are treated with anti-TNF-α therapies (i.e., biologics) (Lichtenstein G R, Hanauer S B, Sandborn W J, Practice Parameters Committee of American College of Gastroenterology, Management of Crohn's disease in adults, Am J Gastroenterol., 2009, 104(2):465-83; Dignass A, Van Assche G, Lindsay J O, et al., European Crohn's and Colitis Oganisation (ECCO), The second European evidence-based Consensus on the diagnosis and management of Crohn's disease: current management, J Crohn's Colitis, 2010, 4(1):28-62, Erratum in: J Crohn's Colitis, 2010, 4(3):353). Potential risks with biologics include infusion or injection site reactions, serious infections, lymphoma and other malignancies, heart failure, cytopenias, lupus-like syndromes, and demyelinating conditions (Sandborn W J, State-of-the-art: immunosuppression and biologic therapy, Dig. Dis., 2010, 28(3):536-42).

Despite the beneficial results achieved with the available anti-TNF-α agents, approximately 40% of patients who receive them for the first time do not have a clinically meaningful response (primary nonresponders) (Targan S R, Hanauer S B, van Deventer S J, et al., A short-term study of chimeric monoclonal antibody cA2 to tumor necrosis factor alpha for Crohn's disease, N Engl. J. Med., 1997, 337(15):1029-35; Hanauer S B, Feagan B G, Lichtenstein G R, et al., ACCENT I Study Group, Maintenance infliximab for Crohn's disease: the ACCENT I randomized trial, Lancet, 2002, 359(9317):1541-9; Hanauer S B, Sandborn W J, Rutgeerts P, et al., Human anti-tumor necrosis factor monoclonal antibody (adalimumab) in Crohn's disease: the CLASSIC-I trial, Gastroenterology, 2007, 132(1):52-65; Colombel J F, Sandborn W J, Rutgeerts P, et al., Adalimumab for maintenance of clinical response and remission in patients with Crohn's disease: the CHARM trial, Gastroenterology, 2007, 132(1):52-65; Sandborn W J, Feagan B G, Stoinov S, et al., PRECISE I Study Investigators, Certolizumab pegol for the treatment of Crohn's disease, N Engl. J Med., 2007, 357(3):228-38). Among patients who initially respond and continue to receive maintenance treatment for longer durations, approximately 38% become nonresponders after 6 months (Schribeinger S, Khaliq-Kareemi M, Lawrance I C, et al; PRECISE 2 Study Investigators, Maintenance therapy with certolizumab pegol for Crohn's disease, N Engl. J Med., 2007, 357(3):239-50, Erratum in: N Engl. J Med., 2007, 357(13):1357) and approximately 50% become nonresponders at 1 year lose response (secondary nonresponders) (Hanauer S B, Feagan B G, Lichtenstein G R, et al., ACCENT I Study Group, Maintenance infliximab for Crohn's disease: the ACCENT I randomized trial, Lancet, 2002, 359(9317):1541-9; Colombel J F, Sandborn W J, Rutgeerts P, et al., Adalimumab for maintenance of clinical response and remission in patients with Crohn's disease: the CHARM trial, Gastroenterology, 2007, 132(1):52-65). Patients who initially respond to a first anti-TNF agent but then lose response tend to have lower response and remission rates to the second anti-TNF agent (Colombel J F, Sandborn W J, Rutgeerts P, et al., Adalimumab for maintenance of clinical response and remission in patients with Crohn's disease: the CHARM trial, Gastroenterology, 2007, 132(1):52-65; Sandborn, et al., “Natalizumab induction and maintenance therapy for Crohn's disease,” N Engl. J. Med., 2005, 353(18):1912-25).

New classes of biologics have been studied in patients with prior anti-TNF use. Natalizumab, a humanized monoclonal antibody to α4β1 and α4β7 integrins, showed promise for patients with prior exposure to anti-TNF-α therapy; more than half of the patients had a response to the induction regimen (Sandborn, et al., “Natalizumab induction and maintenance therapy for Crohn's disease,” N. Engl. J. Med., 2005, 353(18):1912-25). However, natalizumab's use after approval in 2008 has been severely limited due to the serious risk for progressive multifocal leukoencephalopathy (PML) attributed to activation of the latent JC virus (Van Assche G, Van Ranst M, Sciot R, et al., “Progressive multifocal leukoencephalopathy after natalizumab therapy for Crohn's disease,” N. Engl. J. Med., 2005, 353(4):362-8). Vedolizumab is specific to the α4β7 integrin, which does not affect lymphocyte trafficking to the brain. Therefore, it is presumed to not have the PML risk associated with natalizumab. However, it does not fulfill many of the unmet needs of patients who have failed treatment with anti-TNFs, such as the improvement of extra-intestinal manifestations (Rubin, et al., Inflammatory Bowel Diseases, 2016, 22 Suppl. 1: S42-S43). In the induction study with vedolizumab, the primary endpoint of clinical remission in patients who had previously failed treatment with an anti TNF was not statistically significant nor was it clinically meaningful since there was only a 3% difference from placebo (Sands, et al., “Effects of Vedolizumab Induction Therapy for Patients with Crohn's Disease in Whom Tumor Necrosis Factor Antagonist Treatment Failed,” Gastroenterology, 2014, 147:618-627). Ustekinumab, a human monoclonal antibody that selectively targets IL-12 and IL-23, has efficacy in both patients who have responded to and patients who have not responded to prior anti-TNFα therapy. The efficacy of ustekinumab, however, is broadly similar to that of anti-TNF agents, and therefore subject to similar drawbacks (Ther. Adv. Gastroenterology, 2016, Vol. 9(1), pp. 26-36). Clearly, the need for additional therapeutic options in CD for patients who fail or are intolerant to conventional therapies, and anti-TNF-α agents or other biologic therapies remains.

II. JAK1-Associated Disorders and JAK1 Inhibitors

In one aspect, the present disclosure provides methods for treating and/or inducing clinical remission, endoscopic improvement, and/or endoscopic remission of Crohn's disease. In another aspect, the present disclosure provides methods for treating ulcerative colitis and/or for inducing a clinical remission of ulcerative colitis. In one aspect, the methods comprise administering a JAK1 inhibitor to the patient.

Targeting the JAK (Janus activated kinase) signaling pathway for autoimmune diseases, such as rheumatoid arthritis (RA) and CD, is well-supported by the involvement of various pro-inflammatory cytokines that signal via JAK pathways in the pathogenesis of these immune-related disorders. The activation of the JAK signaling initiates expression of survival factors, cytokines, chemokines, and other molecules that facilitate leukocyte cellular trafficking and cell proliferation, which contribute to inflammatory and autoimmune disorders.

Although the pathogenesis of CD is not completely understood, the imbalance between anti-inflammatory and pro-inflammatory cytokines in the mucosal immune system is thought to play an important role in CD. Cells from the innate mucosal immune system, i.e. TH1 or TH17, are over-activated and secrete various pro-inflammatory cytokines such as interferon (INF)-g, TNFα, interleukin IL-6, IL 1b, IL-12, IL23. These cytokines signal via JAK pathways.

The JAK comprises four family members: JAK1, 2, 3, and Tyrosine kinase 2 (Tyk2). These cytoplasmic tyrosine kinases transduce cytokine-mediated signals, and are associated with membrane cytokine receptors such as common gamma-chain (CGC) receptors and the glycoprotein 130 (gp130) trans-membrane proteins.

JAK3 and JAK1 are components of the CGC cytokine receptor complexes and blockade of either inhibits signaling by the inflammatory cytokines IL-2, -4, -7, -9, -15 and -21. Cytokines such as IL-6 bind to gp130 and transduce its signal predominantly via JAK1. Targeting the IL-6 receptor (IL-6R) is a promising approach given the fact that expression of IL-6 and soluble IL-6 receptors is elevated in patients with active CD. Further, a proof of concept study in patients with active CD with tocilizumab, a humanized monoclonal antibody against IL-6R, showed an encouraging clinical response. Thus, inhibition of JAK1 is expected to attenuate the signaling of IL-6 and other pro-inflammatory cytokines (i.e. IFN-g), that are involved in development of CD.

Thus, in one aspect, the present disclosure provides a compound useful in the treatment of Crohn's Disease and ulcerative colitis. In one aspect, the JAK1 inhibitor used in the methods of the present disclosure is the compound (3 S,4R)-3-ethyl-4-(3H-imidazo[1,2-a] pyrrolo[2,3-e]pyrazin-8-yl)-N-(2,2,2-trifluoroethyl)pyrrolidine-1-carboxamide (C₁₇H₁₉F₃N₆O), or a pharmaceutically acceptable salt or solid state form thereof. The compound (3S,4R)-3-ethyl-4-(3H-imidazo[1,2-a]pyrrolo[2,3-e]pyrazin-8-yl)-N-(2,2,2-trifluoroethyl)pyrrolidine-1-carboxamide is also referred to herein as “upadacitinib”, and has the structure shown below:

“Pharmaceutically acceptable salts” refers to those salts which retain the biological effectiveness and properties of the free bases and which are obtained by reaction with inorganic acids, for example, hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, and phosphoric acid or organic acids such as sulfonic acid, carboxylic acid, organic phosphoric acid, methanesulfonic acid, ethanesulfonic acid, p-toluenesulfonic acid, citric acid, fumaric acid, maleic acid, succinic acid, benzoic acid, salicylic acid, lactic acid, mono-malic acid, mono oxalic acid, tartaric acid such as mono tartaric acid (e.g., (+) or (−)-tartaric acid or mixtures thereof), amino acids (e.g., (+) or (−)-amino acids or mixtures thereof), and the like. These salts can be prepared by methods known to those skilled in the art

Unless otherwise indicated, the SF and AP scores discussed herein refer to their respective unweighted average of the daily scores that are used in calculation of the CDAI (discussed below). Measures for assessing health-related quality of life include the Inflammatory Bowel Disease Questionnaire (IBDQ). The IBDQ is a well-known 32 item validated questionnaire that assesses a patient's inflammatory bowel disease symptoms, general well-being, and mood, and may be used as a tool to evaluate a patient's quality of life (Guyatt, et al., Gastroenterology, 1989, 96:804-810). The IBDQ questionnaire is described in further detail below.

CDAI is a composite score used to quantify symptoms of patients with Crohn's disease. In one aspect, the index consists of eight factors added together after adjusting for a predefined weighting factor (see Table 1 below). CDAI scores range from 0 to 600. Index values of 150 and below are associated with quiescent disease; values above 150 are associated with active disease, and values above 450 are seen with extremely severe disease. In one aspect, a patient to be treated by a method according to the present disclosure has a CDAI score of 220 to 450 prior to treatment, which may be indicative of moderately to severely active CD.

The Work Productivity and Activity Impairment Questionnaire for Ulcerative Colitis (WPAI:UC) and Crohn's Disease (WPAI:CD) assesses the impact of the condition on work productivity losses and impairment in daily activity. WPAI:UC has six items covering four domains: Absenteeism (work time missed), measured as the number of hours missed from work in the past 7 days due to a condition related problem. Scores are expressed as impairment percentages, adjusting for hours actually worked according to the WPAI:UC or WPAI:CD scoring algorithm; Presenteeism (impairment at work/reduced on-the-job effectiveness), measured as the impact of the condition on productivity while at work (i.e., reduced amount or kind of work, or not as focused as usual). Responses are recorded on a 0-10 Likert scale (where, 0=no effect of UC or CD on work and 10=severe impact of UC or CD while at work); productivity loss (overall work impairment), measured as the sum of hours missed due to condition i.e., absenteeism and number of hours worked with impairment i.e., product of number of hours worked and presenteeism; and activity impairment (i.e., activities other than paid work like work around house, cleaning, shopping, traveling, studying), recorded and scored in the same way as presenteeism. Higher numbers indicate greater impairment and less productivity. The WPAI:UC/WPAI:CD questions and answer options are set forth in Table 7.

TABLE 7 WPAI:UC* and WPAI:CD Questions Answer Options 1. Are you currently employed (working for pay)? No or yes If no, skip to question 6. 2.

The European Quality of Life 5 Dimensions 5 Levels (EQ-5D-5L) is a standardized non-disease specific instrument for describing and valuing health-related quality of life. The EQ-5D-5L consists of 5 dimensions: mobility, self-care, usual activity, pain/discomfort, and anxiety/depression. Each dimension has 5 levels: no problem, slight problem, moderate problem, severe problem or unable to do the activity. It also contains a Visual Analogue Scale (VAS). Subjects are asked to indicate the level that describes their current level of function or experience for each dimension. As a measure of health status, it provides a descriptive profile and can be used to generate a single index value for health status, where full health is equal to 1 and death is equal to 0. The VAS records the subject's assessment of his/her own health along a vertical 20 cm line, which has health state scores between 0 and 100. The EQ-5D-5L questions and answer options are set forth in Table 8.

The SF-36 questionnaire is a self-administered multi-domain scale with 36 items. Eight subscales cover a range of functioning: physical functioning (PF), role-physical (RP), bodily pain (BP), general health (GH), vitality (VT), social functioning (SF), role-emotional (RE), and mental health (MH). The scoring yields a physical component score, a mental component summary score, and subscale scores. Higher scores represent better outcomes. The concepts measured by the SF-36 are not specific to any age, disease, or treatment group, allowing comparison of relative burden of different diseases and the benefit of different treatments. The SF-36 questions and answer options are set forth below in Table 9.

The Functional Assessment of Chronic Illness Therapy (FACIT) system is a collection of quality of life (QOL) questionnaires targeted to the management of cancer and other chronic illnesses. The FACIT fatigue (FACIT-F) questionnaire was developed to assess fatigue associated with anemia. It consists of 13 fatigue-related questions. The responses to the 13 items on the FACIT fatigue questionnaire are each measured on a 4-point Likert scale. The responses to the answers are the following: (i) not at all: 0 points; (ii) a little bit: 1 point; (iii) somewhat: 2 points; (iv) quite a bit: 3 points; and (v) very much: 4 points. Thus, the total score ranges from 0 to 52. High scores represent less fatigue. The FACIT-F questions and answer options are set forth below in Table 10.

TABLE 10 FACIT-F Questionnaire Answer Question Options I feel fatigued . . . 0 Not at all I feel weak all over . . . 1 A little bit I feel listless (“washed out”) . . . 2 Somewhat I feel tired . . . 3 Quite a bit I have trouble starting things because I am tired . . . 4 Very much I have trouble finishing things because I am tired . . . I have energy . . . I am able to do my usual activities . . . I need to sleep during the day . . . I am too tired to eat . . . I need help doing my usual activities . . . I am frustrated by being too tired to do the things I want to do . . . I have to limit my social activity because I am tired . . .

The Ulcerative Colitis Symptoms Questionnaire (UC-SQ) is a UC-specific instrument composed of 17 Likert-type items. UC-SQ was developed to assess UC related gastrointestinal and non-gastrointestinal symptoms such as frequent bowel movements, abdominal discomfort, nausea, loss of appetite, pain, and anemia along with the impact on patients' sleep. Each question can be answered using Likert-type options such as (i) Not at all: 0 points; (ii) A little bit: 1 point; (iii) Somewhat: 2 points; (iv) Quite a bit: 3 points; and (v) Very much: 4 points based on how the patient felt during the past week (i.e., 7 days). The total score ranges can vary from 0 to 68 with lower scores indicating improvement. The UC-SQ questions and answer options are set forth below in Table 11.

During the past week, did you experience a sudden or intense need to have a bowel movement?

The Patient Global Impression of Change (PGIC) is a self-administered instrument that assesses change in the overall symptoms due to Ulcerative Colitis. The PGIC is one item in which subjects are asked to rate overall improvement since start of the treatment. Patients are asked the question “Compared to before your treatment began, how would you rate the change in your overall symptoms due to your ulcerative colitis?”, and rate their change as “Very much improved,” “Much improved,” “Minimally improved”, “No change,” “Minimally worse,” “Much worse” and “Very much worse”.

No. 8,426,411, the entire content of which is incorporated herein by reference. In one embodiment, upadacitinib, and pharmaceutically acceptable salts thereof, may be synthesized according to the methods described in U.S. patent application Ser. No. 15/295,561, which is herein incorporated by referenced. For example, upadacitinib may be synthesized using synthetic transformations such as those illustrated in Schemes I-IIIa. Starting materials are commercially available, may be prepared by the procedures described in U.S. patent application Ser. No. 15/295,561, by literature procedures, or by procedures that would be well known to one skilled in the art of organic chemistry (see, for example, Larock, R. C. “Comprehensive Organic Transformations: A Guide to Functional Group Preparations, 2^(nd) edition”, 1999, Wiley-VCH or Greene, T. W. and Wuts, P. G. M. “Protective Groups in Organic Synthesis, 3^(rd) Edition”, 1999, Wiley-Interscience).

A process for preparing upadacitinib is illustrated in Scheme I. Reaction of protected (3R,4S)-4-ethylpyrrolidine-3-carboxylic acid (I) or a pharmaceutically acceptable salt thereof with trimethylsulfoxonium chloride gives sulfur ylide (II). Contacting sulfur ylide (II) with LiX and a sulfonic acid yields the corresponding halomethyl ketone (III). Reaction of (III) with (IV) in the presence of a base yields (V). Cyclization of (V) in the presence of a perfluoro acid anhydride and an organic base produces (VI). Removal of the protecting group and contacting the deprotected compound with an acid yields a pharmaceutically acceptable salt of (VII). Reacting the pharmaceutically acceptable salt of (VII) with 2,2,2-trifluoroethylamine produces upadacitinib.

wherein:

PG is a protecting group;

X is Br or Cl;

R₁ is selected from the group consisting of alkyl, aryl, and —OR₂;

R₂ is alkyl; and

Ts is tosyl.

The protecting group may be any suitable protecting group known in the art. In some embodiments, the protecting group is selected from the group consisting of carboxybenzyl, p-methoxybenzyl carbonyl, benzyl, p-methoxybenzyl, and 3,4-dimethoxyenzyl. In another embodiment, the protecting group is carboxybenzyl.

In another embodiment, R₁ is —OR₂, and R₂ is methyl or ethyl. In such embodiments, the compound of formula (IV) is a compound of formula (IVa):

wherein R₂ is methyl or ethyl.

In certain embodiments, a pharmaceutically acceptable salt of a compound of the compound of formula (I) is used in the reaction of step (a). In one embodiment, the pharmaceutically acceptable salt of the compound of formula (I) is selected from the group consisting of the naphthalenethane amine salt (Ia) and the dicyclohexylamine salt (Ib)

wherein Cbz is carboxybenzyl.

In one embodiment, the pharmaceutically acceptable salt of compound (VII) is selected from the group consisting of (VIIa), (VIIb), and (VIIc)

Another process for preparing upadacitinib is illustrated in Scheme Ia. Reaction of (3R,4S)-1-((benzyloxy)carbonyl)-4-ethylpyrrolidine-3-carboxylate dicyclohexylamine salt (Ib) with trimethylsulfoxonium chloride in the presence of carbonyldiimidazole and a strong base gives sulfur ylide (IIa). Contacting sulfur ylide (IIa) with lithium bromide and a sulfonic acid yields the corresponding bromomethyl ketone (IIIa). Reaction of (IIIa) with alkyl 5-tosyl-5H-pyrrolo[2,3-b]pyrazin-2-ylcarbamate (IVa) in the presence of lithium tert-butoxide yields (Va). Cyclization of (Va) in the presence of a perfluoro acid anhydride and an organic base produces (VIa). Removal of the carboxybenzyl protecting group and contacting the deprotected compound with hydrochloric acid yields the pharmaceutically acceptable salt (VIIa). Reacting the pharmaceutically acceptable salt (VIIa) with 2,2,2-trifluoroethylamine produces upadacitinib.

wherein:

Cbz is carboxybenzyl;

Ts is tosyl; and

R₂ is methyl or ethyl.

The reaction in step (a) of Schemes I and Ia is generally accomplished in the presence of a coupling agent, such as carbonyldiimidazole (CDI), and a strong base. The strong base may be, for example, potassium tert-butoxide, sodium tert-butoxide, or combinations thereof. The step (a) reaction may be conducted in any suitable solvent including, but not limited to, tetrahydrofuran, water, and methyl tert-butyl ether.

In one embodiment, the reaction is quenched, and, in some embodiments, the resulting product (V) or (Va) is isolated prior to step (d).

In step (d) of Schemes I and Ia, a compound of formula (V) or (Va) is contacted with a perfluoro acid anhydride and an organic base to form a compound of formula (VI) or (VIa), respectively.

In step (e) of Schemes I and Ia, a compound of formula (VI) or (VIa) is deprotected, and a pharmaceutically acceptable salt of compound (VII), such as (VIIa), (VIIb), or (VIIc) is formed. The protecting group on the compound of formula (VI) or (VIa) may be removed using any suitable means known in the art. In one embodiment, deprotection occurs by contacting the compound of formula (VI) or (VIa) with palladium on carbon (e.g., Pd/C or Pd(OH₂)/C) under hydrogen pressure. In other embodiments, deprotection occurs by contacting the compound of formula (VI) or (VIa) with an acid. Non-limiting examples of suitable acids include hydrochloric acid (HCl), hydrobromic acid (HBr), hydrobromic acid in acetic acid (e.g., HBr/HOAc), and the like. In other embodiments, deprotection occurs by subjecting the compound of formula (VI) or (VIa) to heating, e.g., at a temperature of from room temperature to about 85° C., including about 50° C. Upon deprotection, the compound of formula (VII) is contacted with the appropriate acid (e.g., hydrochloric acid or p-toluenesulfonic acid) to form the pharmaceutically acceptable salt.

Reaction of protected (3R,4S)-4-ethylpyrrolidine-3-carboxylic acid (I) or a pharmaceutically acceptable salt thereof with trimethylsulfoxonium chloride gives sulfur ylide (II). Contacting sulfur ylide (II) with LiX and a sulfonic acid yields the corresponding halomethyl ketone (III). Reaction of (III) with (IV) in the presence of a base yields (V). Cyclization of (V) in the presence of a perfluoro acid anhydride and an organic base produces (VI). Removal of the protecting group and contacting the deprotected compound (VII) (not shown) with hydrochloric acid yields pharmaceutically acceptable salt (VIIb). The pharmaceutically acceptable salt (VIIb) is converted to the freebase (VII), which is reacted with 2,2,2-trifluoroethylamine to produce upadacitinib. Upadacitinib is contacted with L-tartaric acid to form the corresponding tartrate salt, followed by formation of the upadacitinib freebase.

In step (h) of Scheme II, upadacitinib is contacted with L-tartaric acid to form the corresponding tartrate salt (step (h)). Formation of the tartrate salt advantageously aids in removal of impurities prior to isolation of the freebase. The tartrate salt is subsequently converted back to the freebase form (step (i)) to produce upadacitinib. In particular, in step (i) the tartrate salt may be contacted with a base, such as an inorganic base, to produce the corresponding freebase. Suitable bases include, but are not limited to, sodium bicarbonate, sodium carbonate, sodium hydroxide, potassium carbonate, potassium bicarbonate, potassium hydroxide, and the like, or combinations thereof.

An alternate process for preparing upadacitinib is illustrated in Scheme III. Compound (XIa) is hydrogenated to produce (I). Reaction of protected (3R,4S)-4-ethylpyrrolidine-3-carboxylic acid (I) with trimethylsulfoxonium chloride gives sulfur yilde (II). Contacting sulfur yilde (II) with an anhydrous source of HBr or HCl yields the corresponding halomethyl ketone (III). Reaction of (III) with (IV) in the presence of a base yields (V). Cyclization of (V) in the presence of a perfluoro acid anhydride and an organic base produces (VI). Removal of the protecting group and contacting the deprotected compound with an acid yields a pharmaceutically acceptable salt of (VII). Reacting the pharmaceutically acceptable salt of (VII) with 2,2,2-trifluoroethylamine produces upadacitinib.

wherein:

PG is a protecting group; X is Br or Cl;

R₁ is selected from the group consisting of alkyl, aryl, and —OR₂;

In another embodiment, the protecting group is carboxybenzyl.

In another embodiment, R₁ is —OR₂, and R₂ is methyl or ethyl. In such embodiments, the compound of formula (IV) is a compound of formula (IVa):

wherein R₂ is methyl or ethyl. It has surprisingly been discovered that when R₂ is ethyl or methyl, the compound of formula (V) and subsequent downstream compounds can be isolated as crystalline solids, which aids in purification of these intermediates. In contrast, previously known processes, which use compounds where R₂ is t-butyl, result in formation of compounds of formula (V) which are isolated as amorphous solids.

Another process for preparing upadacitinib is illustrated in Scheme IIIa. 1-((benzyloxy)carbonyl)-4-ethyl-2,5-dihydro-1H-pyrrole-3-carboxylic acid (XI) is hydrogenated to produce (XII). Reaction of (3R,4S)-1-((benzyloxy)carbonyl)-4-ethylpyrrolidine-3-carboxylate (XII) with trimethylsulfoxonium chloride gives sulfur yilde (IIa). Contacting sulfur yilde (IIa) with an anhydrous source of HBr yields the corresponding bromomethyl ketone (IIIa). Reaction of (IIIa) with alkyl 5-tosyl-5H-pyrrolo[2,3-b]pyrazine-2-ylcarbamate (IVa) in the presence of lithium tert-butoxide yields (Va). Cyclization of (Va) in the presence of a perfluoro acid anhydride and an organic base produces (VIa). Removal of the carboxybenzyl protecting group and contacting the deprotected compound with hydrochloric acid yields the pharmaceutically acceptable salt (VIIa). Reacting the pharmaceutically acceptable salt (VIIa) with 2,2,2-trifluoroethylamine produces upadacitinib.

wherein:

Cbz is carboxybenzyl; Ts is tosyl; and R₂ is methyl or ethyl.

In step (a) of Schemes III and IIIa, (XIa) or (XI) (which may be prepared as described in Scheme V) is converted to (I) or (XII), respectively. In particular, in step (a), compound (XI) or (XIa) may be contacted with a catalyst, such as a ruthenium catalyst. Any catalyst comprising a chiral phosphine may be used. One particular example of a suitable catalyst is diacetato[(S)-(−)5,5′-bis(diphenylphosphino)-4,4′-bi-1,3-benzodioxole]ruthenium(II) (i.e., (S)-Segphos Ru(OAc)₂) Suitable solvents for use in step (a) include, but are not limited to, methanol, triethylamine, and combinations thereof.

In one embodiment, the suspension is cooled to a temperature of about −1° C. or less, or to about −5° C. or less. In some embodiments, the concentrated filtrate from step (a) is diluted with a suitable solvent (e.g., tetrahydrofuran), and to this solution is slowly added (e.g., over 30 minutes to 1 hour, or over 30 minutes) CDI. The resulting mixture is stirred at room temperature for 30 minutes to 12 hours, and typically for about 1 hour. The resulting solution is slowly added (e.g., over 15 minutes to 1 hour, or over 1 hour) to the suspension of the trimethylsulfoxonium chloride, strong base, and solvent, while maintaining the internal temperature below −1° C. In embodiments, the reaction may be stirred for about 30 minutes to about 8 hours, or for about 1 hour at a temperature of below about −1° C., or at about −5° C. In another embodiment, the reaction is quenched and the resulting compound of formula (II) or (IIa) is isolated prior to step (c).

Steps (a) and (b) of Schemes III and IIIa advantageously allow for preparation of a protected (3R,4S)-4-ethylpyrrolidine-3-carboxylic acid without formation and isolation of the naphthalenethane amine salt (Ia) or the dicyclohexylamine salt (Ib), or isolation of (I) or (XI).

In step (c) of Schemes III and IIIa, a compound of formula (II) or (IIa) is contacted with an anhydrous source of HBr or HCl to form a compound of formula (III) or (IIIa), respectively. In particular, the anhydrous source of HBr or HCl comprises no more than 0.2% water (by volume), or no more than about 0.15% water (by volume).

In one embodiment, the suspension of the compound of formula (IV) or (IVa) is cooled to about 0° C.

VI. Solid State Forms

The present disclosure also relates to the use of solid state forms of upadacitinib in the treatment of Crohn's disease and ulcerative colitis. Solid state forms include the Amorphous Freebase form of upadacitinib, Freebase Solvate Form A, Freebase Hydrate Form B, Freebase Hydrate Form C, Tartrate Hydrate, and Freebase Anhydrate Form D. These and other solid state forms of upadacitinib are described in U.S. patent application Ser. No. 15/295,561, which is herein incorporated by reference. The sections below also discuss solid state forms that have been identified and selected properties of those solid state forms.

A. Amorphous Freebase

In one embodiment, the solid state form is amorphous upadacitinib (the “Amorphous Freebase”). In one aspect, the Amorphous Freebase comprises less than about 13% by weight water. In another aspect, the Amorphous Freebase comprises less than about 12% by weight water. In another aspect, the Amorphous Freebase comprises less than about 10% by weight water. In another aspect, the Amorphous Freebase comprises less than about 9% by weight water. In another aspect, the Amorphous Freebase comprises less than about 8% by weight water. In another aspect, the Amorphous Freebase comprises less than about 7% by weight water. In another aspect, the Amorphous Freebase comprises less than about 6% by weight water. In another aspect, the Amorphous Freebase comprises less than about 5% by weight water. In another aspect, the Amorphous Freebase comprises less than about 4% by weight water. In another aspect, the Amorphous Freebase comprises less than about 3% by weight water. In another aspect, the Amorphous Freebase comprises less than about 2% by weight water. In another aspect, the Amorphous Freebase comprises less than about 1% by weight water. In another aspect, the Amorphous Freebase has a glass transition temperature onset at about 119° C. In another aspect, the Amorphous Freebase has a glass transition temperature midpoint at about 122° C. In another aspect, the Amorphous Freebase has a glass transition temperature onset at about 119° C. and a glass transition temperature midpoint at about 122° C.

The Amorphous Freebase generally has greater solubility, and increased bioavailability, relative to the corresponding crystalline forms of the compound. The Amorphous Freebase also has acceptable chemical stability. In addition, the Amorphous Freebase exhibits acceptable stability to light and peroxide. The Amorphous Freebase, however, is hygroscopic and can comprise as much as 12% by weight water at 25° C./90% relative humidity. Environmental controls potentially are required to ensure appropriate control of potency and water content during storage, dispensing, and handling of the Amorphous Freebase.

The Amorphous Freebase can be prepared, for example, using anti-solvent crystallization to prepare the Freebase Solvate Form A or Freebase Hydrate Form B (described below) followed by dehydration or desolvation to yield the Amorphous Freebase. This crystallization/dehydration/desolvation method allows for the large-scale manufacture of the Amorphous Freebase without the need for labor-intensive and expensive techniques such as spray-drying. It also provides for appropriate control of the bulk properties of the Amorphous Freebase (i.e., particle size, flow properties etc.). When the Amorphous Freebase is prepared by desolvation of the Freebase Solvate Form A or dehydration of the Freebase Hydrate Form B, the Amorphous Freebase generally retains the morphology of the Freebase Solvate Form A or Freebase Hydrate Form B (i.e., blades with hexagonal crystal faces when prepared by dehydration of Freebase Hydrate Form B, or irregular when desolvated from Freebase Solvate Form A).

The process volumes required for crystallization during the large-scale manufacture of the Freebase Solvate Form A or Freebase Hydrate Form B generally are within conventional processing volumes, but impurity rejection potentially may be lower than desired. Drying and dehydration/desolvation of the Freebase Hydrate Form B/Freebase Solvate Form A to the Amorphous Freebase generally can be carried out with standard equipment under conventional conditions and the isolated Amorphous Freebase typically can be co-milled without adversely impacting the amorphous state.

In one embodiment, the Tartrate Hydrate has an X-ray powder diffraction pattern characterized by peaks at 3.9±0.2, 6.8±0.2, 14.1±0.2, 15.7±0.2, 21.9±0.2 degrees two theta, and without a significant peak at one or more of 3.1±0.2, 9.3±0.2, and 12.0±0.2 degrees two theta.

In one embodiment, the Tartrate Hydrate has an X-ray powder diffraction pattern characterized by peaks at 3.9±0.2, 6.8±0.2, 14.1±0.2, 15.7±0.2, 21.9±0.2 degrees two theta, and without a significant peak at one or more of 13.4±0.2 and 15.1±0.2 degrees two theta, and without a significant peak at one or more of 3.1±0.2, 9.3±0.2, and 12.0±0.2 degrees two theta.

In further aspects of each of the above embodiments, the significant peak values have a variation of ±0.1 degrees two theta rather than ±0.2 degrees two theta. In still further aspects of each of the above embodiments, the significant peak values have a variation of ±0.05 degrees two theta rather than ±0.2 degrees two theta.

In one embodiment, the Tartrate Hydrate has an X-ray powder diffraction pattern substantially as shown in FIG. 21 , when measured at about 25° C. with monochromatic Kα1 radiation.

The Tartrate Hydrate has acceptable chemical stability and exhibits acceptable stability to light and peroxide. The Tartrate Hydrate has good solubility (BCS Class I) and is not hygroscopic. The Tartrate Hydrate, however, potentially will convert to an amorphous tartrate below 10% relative humidity, when heated, or when compressed or under shear.

The Tartrate Hydrate can be manufactured, for example, using anti-solvent crystallization. Impurity rejection during the large-scale manufacture of the Tartrate Hydrate generally is good, but scaling may be greater than desired and specific anti-solvent addition controls and process volume restrictions potentially may be required. In addition, appropriate control of the filtration, washing, and drying steps may be required to minimize consolidation of the wet cake and formation of hard lumps in the isolated material. For example, control of the relative humidity (e.g., greater than 10% and less than 100% relative humidity), temperature (e.g., crystallization at about 10° C. works well), and mixing rate may be required during drying to minimize the formation of hard lumps in the isolated material. Insufficient control of the drying conditions potentially will produce a consolidated, harder material that may be difficult to break up during subsequent processing. As previously noted, shearing and compression potentially will cause conversion to the amorphous tartrate. The dried material typically is milled with mechanical impact mills (e.g., Fitzmills and pin mills) because shear-based mills (e.g., comills) can lead to loss of crystallinity. In addition, loss of crystallinity potentially can result from pressure or compression forces during formulation (such as would be required for tableting).

The solvent or mixture of solvents will be water-free, or close to water-free. In embodiments, the solvent or mixture of solvents will have a water content of less than about 0.15 wt %, or less than about 0.10 wt. %, or less than about 0.05 wt. %, or about 0 wt. % at 23° C. In one embodiment, the solvent or mixture of solvents will have a water activity of about 2.4% or less, or about 2.2% or less, or about 2.0% or less, or about 1.5% or less. The solvent or mixture of solvents can comprise, for example, ethyl acetate (EtOAc), heptane, and combinations thereof. In one embodiment, the solvent system comprises a mixture of heptane in ethyl acetate.

E. Preparation of Crystalline Tartrate Hydrate

The present disclosure additionally relates to methods for preparing the Tartrate Hydrate.

The solvent or mixture of solvents also can comprise an anti-solvent (such as isopropyl acetate). In certain aspects, the process further comprises seeding the solvent or mixture of solvents with crystals of the Tartrate Hydrate.

The crystallization generally is conducted at a temperature less than about 40° C. When an anti-solvent is used, a moderate rate of addition is employed for the anti-solvent as a faster rate of addition typically results in the precipitation of an amorphous tartrate and a slower rate of addition allows the resulting slurry to thicken. Proper control of filtration, washing, and drying may be needed to avoid potential issues associated with consolidation of the filter cake, including solvent entrapment, solid properties (e.g., hard, chunky solids) and handing, and damage to equipment. Depending upon the properties of the dried Tartrate Hydrate material, milling may require a mechanical impact-type of mills rather than a shear-based mill (such as a co-mill).

FIG. 16 schematically illustrates one method of preparing the Tartrate Hydrate.

VIII. Pharmaceutical Compositions and Routes of Administration

One or more compounds of this disclosure can be administered to a human patient by themselves or in pharmaceutical compositions where they are mixed with biologically suitable carriers or excipient(s) at doses to treat or ameliorate a disease or condition as described herein. Mixtures of these compounds can also be administered to the patient as a simple mixture or in suitable formulated pharmaceutical compositions.

The pharmaceutical compositions of the present disclosure may be manufactured in a manner that is itself known, e.g., by means of conventional mixing, dissolving, granulating, dragee-making, levigating, emulsifying, encapsulating, entrapping or lyophilizing processes.

Pharmaceutical compositions for use in accordance with the present disclosure thus may be formulated in a conventional manner using one or more physiologically acceptable carriers comprising excipients and auxiliaries which facilitate processing of the active compounds into preparations which can be used pharmaceutically. Proper formulation is dependent upon the route of administration chosen.

In one embodiment, the active ingredient contained in the dosage unit composition is upadacitinib, or a pharmaceutically acceptable salt or solid state form thereof. In one embodiment, the target or label amount of active ingredient (e.g., upadacitinib) provided for inclusion in the compositions of the present disclosure refers to the amount of upadacitinib freebase. For instance, upadacitinib may be prepared in several solid state forms including Amorphous Freebase, crystalline solvates and hydrates (e.g., Freebase Solvate Form A, Freebase Hydrate Form B), crystalline hemihydrates (e.g., Freebase Hydrate Form C), crystalline anhydrate (e.g., Freebase Anhydrate Form D), and crystalline tartrate (e.g., Tartrate Hydrate). Preparation of these solid state forms is described herein and also in U.S. patent application Ser. No. 15/295,561, which is herein incorporated by reference. It should be understood that in embodiments, where the dosage unit composition comprises, e.g., a solvate, hydrate, hemihydrate, or tartrate of upadacitinib, the amount of solvate, hydrate, hemihydrate, or tartrate of upadacitinib present in the dosage unit composition may be slightly higher than the target amount of upadacitinib (active ingredient), and preferably will be present in the dosage unit composition in an amount sufficient to deliver the target amount of upadacitinib freebase equivalent to a patient. For example, if the target amount of upadacitinib (active ingredient) in a dosage unit composition is 15 mg, a dosage unit composition comprising, for example, a hydrate of upadacitinib, may comprise the hydrate in an amount sufficient to deliver 15 mg of the upadacitinib freebase equivalent.

In one embodiment, the pharmaceutical composition is a tablet dosage form. In one aspect, the tablet is coated with a pharmaceutically acceptable polymer. In one embodiment, the pharmaceutical composition is a capsule dosage form.

In one embodiment, tablet is a controlled-release formulation, such as an extended release tablet dosage form (also referred to herein as a modified release or sustained release formulation). Such formulations permit the sustained release of the active ingredient over an extended period of time, as compared to immediate release solid dosage forms, which permit the release of most or all of the active ingredient over a short period of time (e.g., typically around 60 minutes or less). In one aspect, the tablet comprises an active ingredient (e.g., upadacitinib) and at least one additive selected from the group consisting of a release control polymer, a filler, a glidant, a lubricant (e.g., for use in compacting the granules), a pH modifier, a surfactant, and combinations thereof. In one aspect, the tablet comprises an active ingredient, a release control polymer, a filler, a glidant, and a lubricant. In one aspect, the tablet comprises an active ingredient, a release control polymer, a filler, a glidant, a lubricant, and a pH modifier.

In certain embodiments, the release control polymer will be a hydrophilic polymer. Examples of suitable release control polymers include, but are not limited to a cellulose derivative with a viscosity of between 1000 and 150,000 mPA-s, hydroxypropylmethyl cellulose (e.g., Hypromellose 2208 or controlled release grades of hydroxypropylmethyl cellulose, including the E, F, and K series), copolymers of acrylic acid crosslinked with a polyalkenyl polyether (e.g., Carbopol® polymers), hydroxypropyl cellulose, hydroxyethyl cellulose, non-ionic homopolymers of ethylene oxide (e.g., Polyox™), water soluble natural gums of polysaccharides (e.g., xanthan gum, alginate, locust bean gum, etc.), crosslinked starch, polyvinyl acetates, polyvinylpyrrolidone, mixtures of polyvinyl acetates and polyvinyl pyrrolidone, and combinations thereof. In one embodiment, the release control polymer is selected from the group consisting of hydroxypropylmethyl cellulose, copolymers of acrylic acid crosslinked with a polyalkenyl polyether (e.g., Carbopol® polymers), and combinations thereof. Examples of suitable fillers (“bulking agents”) include, but are not limited to, microcrystalline cellulose (e.g., Avicel® PH 101; Avicel® PH 102;), mannitol (e.g., Pearlitol® 100 SD or Pearlitol® 200 SD), lactose, sucrose, sorbitol, and the like. In one embodiment, the filler is selected from the group consisting of microcrystalline cellulose, mannitol, and combinations thereof. Examples of suitable glidants include, but are not limited to, silicone dioxide (e.g., colloidal silicon dioxide), calcium silicate, magnesium silicate, talc, and combinations thereof. In one embodiment, the glidant is colloidal silicone dioxide. Examples of suitable lubricants include, but are not limited to, polyethylene glycol (e.g., having a molecular weight of from 1000 to 6000), magnesium stearate, calcium stearate, sodium stearyl fumarate, talc, and the like. In one embodiment, the lubricant is magnesium stearate. Examples of suitable pH modifiers include, but are not limited to, organic acids, such as tartaric acid, citric acid, succinic acid, fumaric acid; sodium citrate; magnesium or calcium carbonate or bicarbonate; and combinations thereof. In one embodiment, the pH modifier is tartaric acid. Examples of suitable surfactants include sodium lauryl sulfate.

In one embodiment, the pharmaceutical composition comprises from about 10 w/w % to about 35 w/w % of a pH modifier, and in particular, tartaric acid, fumaric acid, citric acid, succinic acid, malic acid, or combinations thereof. In other embodiments, the formulation comprises from about 20 w/w % to about 35 w/w %, or from about 20 w/w % to about 30 w/w %, or from about 20 w/w % to about 25 w/w %, or about 10 w/w %, about 15 w/w. %, about 20 w/w %, about 25 w/w % or about 30 w/w % pH modifier. In one embodiment, the pH modifier is tartaric acid. Sustained peak plasma concentrations can theoretically be achieved by means of sustained release matrix systems. However, when such systems are made of hydrophilic polymers, such as HPMC, they seldom provide pH independent drug release of pH-dependent soluble drugs, and they are normally incapable of attaining zero-order release except for practically insoluble drugs. Is has been discovered that when a pH modifier, such as tartaric acid, fumaric acid, citric acid, succinic acid, malic acid, or combinations thereof, is used in a hydrophilic sustained release matrix system, it allows upadacitinib or a pharmaceutically acceptable salt or solid state form thereof to be released at a steady rate regardless of the pH of the environment. It has been discovered that as a tablet containing the hydrophilic polymer matrix system erodes, upadacitinib reacts with the HPMC, creating a thicker gel layer which slows the release of upadacitinib from the tablet. The resulting gel layer provides an environment suitable for upadacitinib to dissolve.

Thus, in one embodiment, the pharmaceutical composition of the present disclosure exhibits a pH-independent release of the active ingredient (upadacitinib). Advantageously, it has been discovered that including organic acids, such as a tartaric acid, in the composition as a pH modifier improves the release profile, and results in a pH independent release of the active ingredient. Without wishing to be bound to any particular theory, it is believed that the pH modifier and hydrophilic polymer create a microenvironment in which the active ingredient dissolves, and then is released. The release from the microenvironment occurs at approximately the same rate, regardless of pH. This is particularly advantageous, since the pH of the gastrointestinal tract may vary significantly from the stomach (e.g., pH of about 1.5-3), to the duodenum (e.g., pH of about 4-5), to the lower part of the small intestines (e.g., pH of about 6.5-7.5).

Thus, in one embodiment, the pharmaceutical composition is a modified release formulation comprising upadacitinib, or a pharmaceutically acceptable salt or solid state form thereof, a hydrophilic polymer, and a pH modifier, wherein the hydrophilic polymer, in contact with water, forms a gel layer that provides an environment suitable for upadacitinib, or a pharmaceutically acceptable salt or solid state form thereof, to dissolve. In some embodiments, the environment suitable for upadacitinib, or a pharmaceutically acceptable salt or solid state form thereof, to dissolve has a pH equal to or less than about 3.8 at 37° C. In some such embodiments, the environment has a pH of from about 1.5 to about 3.7, or from about 2.0 to about 3.7, or from about 2.5 to about 3.6, or from about 3.0 to about 3.6, or from about 3.0 to about 3.5.

In one such embodiment, the environment suitable for upadacitinib, or a pharmaceutically acceptable salt or solid state form thereof, to dissolve is as set forth above, and the modified release formulation comprises from about 10 w/w % to about 35 w/w % of a pH modifier, and in particular, tartaric acid, fumaric acid, citric acid, succinic acid, malic acid, or combinations thereof. In other embodiments, the formulation comprises from about 20 w/w % to about 35 w/w %, or from about 20 w/w % to about 30 w/w %, or from about 20 w/w % to about 25 w/w %, or about 10 w/w %, about 15 w/w %, about 20 w/w %, about 25 w/w % or about 30 w/w % pH modifier. In any of these embodiments, the pH modifier may be selected from the group consisting of tartaric acid, fumaric acid, citric acid, succinic acid, malic acid, and combinations thereof. In one such embodiment, the pH modifier is selected from the group consisting of tartaric acid, fumaric acid, citric acid, succinic acid, and combinations thereof. In one such embodiment, the pH modifier is selected from the group consisting of tartaric acid and fumaric acid. In one embodiment, the pH modifier is tartaric acid. In one embodiment, the pH modifier is fumaric acid or citric acid. The weight % tartaric acid set forth herein is by weight of the uncoated composition (e.g., uncoated tablet). In any of the foregoing embodiments, the hydrophilic polymer may be a cellulose derivative with a viscosity of between 1000 and 150,000 mPA-s. In one embodiment, the hydrophilic polymer is selected from the group consisting of hydroxypropylmethyl cellulose, hydroxyethyl cellulose, and mixtures or combinations thereof. In one embodiment, the hydrophilic polymer is hydroxypropylmethyl cellulose. In one embodiment, the hydrophilic polymer is hydroxypropylmethyl cellulose Grade E, F, or K. In one embodiment, the hydrophilic polymer is Hypromellose 2208.

In one embodiment, the tablet is a compressed and/or milled tablet. For example, in some embodiments, the tablet is formed by blending the composition components (e.g., including the active ingredient and at least one pharmaceutically acceptable carrier). The composition can then be either directly compressed, or one or more of the composition components can be granulated prior to compression. In one embodiment, milling is performed using a mill fitted with any suitable size screen (e.g., a fitted with a screen size of from about 600 to about 1400 μm or about 610 μm or about 1397 μm). Compression can be done in a tablet press, such as in a steel die between two moving punches.

In other embodiments, the compressed and/or milled tablet is formulated using a wet granulation process. Use of wet granulation helps reduce and/or eliminate sticking that may occur when compression without wet granulation (e.g., direct compression) is used to formulate the tablets. In one embodiment, the wet granulation process may include the following steps: (a) combining the active ingredient (e.g., upadacitinib or a pharmaceutically acceptable salt or solid state form thereof or a solid state form of upadacitinib) and at least a portion of one additional composition component to form a dry granulation mixture; (b) contacting the dry granulation mixture with a granulation fluid to form a wet granulation mixture; (c) drying the wet granulation mixture to form a granulated material; (d) milling the granulated material to form a milled granulated material; (e) combining the milled granulation material with the remaining composition components; and (f) compressing the composition into the solid dosage unit (e.g., a tablet).

In step (a) of this process, the active ingredient may be combined with, for example, a portion of the release control polymer (e.g., HPMC), a portion of the filler (e.g., microcrystalline cellulose, such as Avicel® PH101), or both a portion of the release control polymer and a portion of the filler to form the dry granulation mixture. Any suitable portion of the release control polymer may be used in step (a). In one embodiment, from about 5 to 10 wt. % or from about 6 to 8 wt. % of the total amount of the release control polymer in the composition is used in step (a).

In certain embodiments, the granulation fluid used in step (b) may comprise water, a suitable solvent (e.g., ethanol, isopropanol, etc.), or combinations thereof. In one embodiment, the granulation fluid comprises water. In one embodiment, the active ingredient may be combined with a portion of the filler, while a portion of the release control polymer (e.g., HPMC) is dissolved in a liquid, such as water, to form the granulation fluid. In one embodiment, the granulation fluid is sprayed on the dry granulation mixture.

The dried granulation material may be milled using, for example, a comill fit with any suitable screen size. In one embodiment, the screen size is from about 600 to about 900 microns, or from about 610 to about 813 microns. In one embodiment, the granulated material is milled using a comill fitted with a 610 μm screen. In one embodiment, the granulated material is milled using a comill fitted with a 813 μm screen.

In step (e), the milled granulation material is combined with any remaining composition components, such as any remaining filler (e.g., microcrystalline cellulose, such as Avicel® PH102), any remaining release control polymer, glidants, lubricants, pH modifiers, surfactants, and the like. In one embodiment, the filler and/or release control polymer included in the granulated material may be the same or different than the filler and/or release control polymer added in step (e). For instance, in one embodiment, the filler included in the granulated material (e.g., Avicel® PH101) may have a smaller particle size distribution than the filler added in step (e) (e.g., Avicer® PH102).

In one embodiment, the composition may be sieved, and the sieved composition blended, for example, after step (e), and prior to compressing the composition (step (f)). In one embodiment, the formulation is sieved prior to addition of any lubricant. In one embodiment, the pH modifier (e.g., tartaric acid) is optionally milled prior to combining with the granulated material.

In some embodiments, the tablet further comprises a film coat. A film coat on the tablet further may contribute to the ease with which it can be swallowed. A film coat can also improve taste and provides an elegant appearance. In certain embodiments, the film-coat includes a polymeric film-forming material such as hydroxypropyl methylcellulose, hydroxypropylcellulose, and acrylate or methacrylate copolymers. Besides a film-forming polymer, the film-coat may further comprise a plasticizer, e.g. polyethylene glycol, a surfactant, e.g. polysorbates, and optionally a pigment, e.g. titanium dioxide or iron oxides. The film-coating may also comprise talc as anti-adhesive. In one embodiment, the film coat accounts for less than 5% by weight of a pharmaceutical composition of the present disclosure.

In another embodiment, the pharmaceutical composition is a capsule dosage form.

For the prevention or treatment of disease, the appropriate dosage of JAK1 inhibitor will depend on a variety of factors such as the type of disease to be treated, as defined above, the severity and course of the disease, whether the JAK1 inhibitor is administered for preventive or therapeutic purposes, previous therapy, the patient's clinical history and response to the antibody, and the discretion of the attending physician. The JAK1 inhibitor is suitably administered to the patient at one time or over a series of treatments.

The JAK1 inhibitor is formulated, dosed, and administered in a fashion consistent with good medical practice. Factors for consideration in this context include the particular disorder being, treated, the particular mammal being treated, the clinical condition of the individual patient, the cause of the disorder, the scheduling of administration, and other factors known to medical practitioners. The “therapeutically effective amount” of the JAK1 inhibitor will be governed by such considerations.

Pharmaceutical compositions suitable for use in the present disclosure include compositions wherein the active ingredients are contained in an effective amount to achieve its intended purpose. More specifically, a therapeutically effective amount means an amount effective to prevent development of or to alleviate the existing symptoms of the patient being treated. Determination of the effective amounts is well within the capability of those skilled in the art. In one particular embodiment, the composition will be a once-daily modified release formulation comprising 7.5 mg, 15 mg, 30 mg, or 45 mg of upadacitinib or a pharmaceutically acceptable salt or solid state form thereof.

IX. Examples Example 1: Preparation of Amorphous Freebase

A. Method A: Precipitation from Water

Upadacitinib (approximately 300 g) was dissolved in water (10 L) and 50% sodium hydroxide (160 g) was added drop-wise over a two hour period to adjust the pH to greater than 12. Solids formed immediately. The solids were filtered, washed with two 500 mL aliquots of water, and then dried in a vacuum oven. The solids were equilibrated for a short period of time at ambient temperature prior to characterization. Conversion to Amorphous Freebase of upadacitinib was confirmed by PXRD analysis.

B. Method B: Dehydration of Freebase Hydrate Form B

A sample of the Freebase Hydrate Form B form of upadacitinib (crystallized from ethanol/water at sub-ambient temperatures as described in Example 2, Method C below) was placed in a vacuum oven at 40° C. overnight. The solids removed from the vacuum oven were equilibrated for a short time at 23° C. prior to characterization. Conversion to Amorphous Freebase of upadacitinib was confirmed by PXRD analysis.

Example 2: Preparation of Freebase Solvate Form A and Freebase Hydrate Form B

A. Method A: Freebase Solvate Form A (Isopropyl Acetate/Water Solvate)

A sample of the Amorphous Freebase of upadacitinib (25 mg) was added to a vial followed by isopropyl acetate (125 μL) and water (10 μL). All solids dissolved at ambient temperature. The solution was placed in a freezer at −16° C. for 4 days. The liquor was decanted and the crystallized solids were isolated. The isolated crystals were analyzed by PXRD while still wet. Conversion to Freebase Solvate Form A (isopropyl acetate/water solvate) of upadacitinib was confirmed by PXRD analysis.

B. Method B: Freebase Hydrate Form B from Methanol/Water

A sample of the Amorphous Freebase of upadacitinib (164 mg) and MeOH (621 mg) were added to a vial. The components were mixed at ambient temperature until the solids dissolved. Water (approximately 680 μL) was added to the vial and the vial was placed in an ice/sodium chloride bath at approximately −3° C. Crystal seeds comprising Freebase Hydrate Form B were added to the vial and the vial was placed in a freezer at −16° C. A sample was pulled from the crystallized suspension and the solids were immediately analyzed with PXRD and TGA-MS. Conversion to Freebase Hydrate Form B of upadacitinib was confirmed by PXRD and TGA-MS analysis.

C. Method C: Freebase Hydrate Form B from Ethanol/Water

A sample of the Amorphous Freebase of upadacitinib (4.2 g) was dissolved in EtOH (15.3 g) in a jacketed reactor. Water (23.3 g) was slowly added to the reactor. The reactor solution was cooled to approximately 2° C. A small portion of a seed solution comprising the Freebase Hydrate Form B was charged to the reactor. The suspension was mixed at approximately 2° C. for 3 hours and water (36 g) in was charged to the reactor in small aliquots over several hours while maintaining the suspension at a temperature of approximately 2° C. The crystallized suspension was mixed at approximately 2° C. and the solids were isolated via filtration. Conversion to Freebase Hydrate Form B of upadacitinib was confirmed by PXRD analysis.

The Freebase Solvate Form A and Freebase Hydrate Form B do not readily crystallize from solution. In general, sub-ambient temperatures and sufficient water activity are needed to crystallize Freebase Solvate Form A and Freebase Hydrate Form B from solution.

Crystalline freebase hydrates and solvates have been isolated from several solvent systems either through primary nucleation (without seeding) or through seeding. In addition to crystallization from isopropyl acetate/water (as described in Method A above), crystalline freebase hydrates or solvates also have been isolated through primary nucleation (without seeding) from, e.g., n-butylamine/water and ethanol/water solvent systems. In addition to crystallization from methanol/water (as described in Method B above) and ethanol/water (as described in Method C above), crystalline freebase hydrates or solvates also have been isolated through seeding from, e.g., acetone/water; acetonitrile/water; ethyl formate/water; methyl acetate/water; ethyl acetate/water; methyl ethyl ketone/water; methyl isobutyl ketone/water, methyl isobutyl ketone/methyl tert-butyl ether/water; and isopropyl acetate/methyl tert-butyl ether/water solvent systems. The Freebase Solvate Form A (isopropyl acetate/water solvate) prepared in Method A above, the Freebase Hydrate Form B prepared in Methods B and C above, and these other crystalline freebase solvates or hydrates that have been prepared are isostructural and exhibit similar PXRD patterns. Notably, these crystalline freebase solvates and hydrates are distinguishable from and exhibit a different PXRD pattern than Freebase Hydrate Form C (a hemihydrate), which is described below.

The Freebase Solvate Form A and Freebase Hydrate Form B that were prepared were not stable after isolation at ambient conditions and readily dehydrated to the Amorphous Freebase.

Example 3: Preparation of Freebase Hydrate Form C

A. Method A: Freebase Hydrate Form C from Ethanol/Water

A sample of the Amorphous Freebase of upadacitinib (2 g) was transferred to a 500 mL beaker equipped with a stirring bar. EtOH (50 g) was added to the beaker and stirred until all solids dissolved. The solution was transferred to a 250 mL jacketed flask equipped with a dispersing device. The solution was cooled to 6° C. Water (150 g) was added to the solution and the solution was subjected to high shear for two hours using the dispersing device. After solid formation was observed, an additional amount of water (50 g) was added to the resulting suspension. The suspension was held overnight at ambient temperature. Solids were isolated and examined on the following day. Conversion to upadacitinib Freebase Hydrate Form C was confirmed by PXRD analysis.

B. Method B: Freebase Hydrate Form C From Ethyl Acetate/Heptane/Water

A crude reaction mixture assaying for 11.1 g of upadacitinib was taken up in 2% water in EtOAc (70 g) and seeded with Freebase Hydrate Form C (100 mg). The suspension was stirred overnight and heptane (70 g) was added. The solids were collected by filtration, washed with water saturated EtOAc/heptane (1/1, 100 mL), and dried under vacuum at 50° C. Conversion to upadacitinib Freebase Hydrate Form C was confirmed by PXRD analysis.

As was observed with the Freebase Solvate Form A and the Freebase Hydrate Form B, the Freebase Hydrate Form C also does not readily crystallize from solution.

Example 4: Preparation of Tartrate Hydrate

Three methods for the preparation of upadacitinib tartrate tetrahydrate (the “Tartrate Hydrate”) are described below. Method A describes an initial procedure that was used to prepare the tartrate tetrahydrate. Method B describes a modified procedure used to prepare the tartrate tetrahydrate at a larger scale. Method C describes a further modified procedure used to prepare the tartrate tetrahydrate. The modified procedure of Method C relative to the procedure of Method B further reduces solidification of the filter cake, a potential problem that potentially can impact manufacturability and downstream processing.

A. Method A

A sample of the Amorphous Freebase of upadacitinib (28.2 mg) was transferred to an amber vial. Water (200 μL) and L-tartaric acid (34.5 mg (approximately 3 equivalents)) were added to the vial. The suspension was vortexed under ambient conditions until all the solids dissolved. The solution in the vial was magnetically stirred at 0° C. The following day, the solids were isolated from the solution and left at ambient temperature for a short period of time prior to characterization. Conversion to the upadacitinib Tartrate Hydrate (tetrahydrate) was confirmed by PXRD analysis.

B. Method B

Upadacitinib (4.6 g) was added to a jacketed reactor followed by the addition of isopropanol (6.5 mL) and IPAc (7.8 mL). The slurry was mixed at ambient condition until the solids dissolved. In a separate vial, L-tartaric acid (1.96 g) was dissolved in deionized water (3.92 mL). The L-tartaric acid solution was added to the reactor followed by the addition of tartrate tetrahydrate seed crystals (28 mg). The suspension was mixed for 30 minutes under ambient conditions. IPAc (71 mL) was added in small aliquots over 2 hours. The crystallized suspension was cooled to 5° C. and equilibrated at 5° C. overnight. The suspension was discharged onto a filter and the filter cake rinsed with 20 mL of water saturated IPAc. The filtered solids were air-dried for two days. Conversion to the upadacitinib Tartrate Hydrate (tetrahydrate) was confirmed by PXRD analysis.

C. Method C

Crystallization: Upadacitinib (104 g) was added to a flask together with isopropanol (222.7 g) and IPAc (375.8 g). The components were mixed under ambient conditions until the solids dissolved. In a separate flask, L-tartaric acid (61.6 g) was dissolved in water (98.3 g). The contents of the two flasks were then added to a jacketed reactor. Tartrate tetrahydrate seed crystals (1.55 g) were added to the reactor solution. The resulting suspension was mixed overnight under ambient conditions. IPAc (2542 g) was charged to the reactor suspension over an 8 hour period.

Filtration, Washing and Drying: Approximately half of the crystallized tartrate suspension was charged to a jacketed agitated filter dryer. The suspension was cooled inside the filter dryer to approximately 11° C. The suspension was filtered using positive pressure until a wet cake was obtained. Water saturated IPAc (438 g) was charged to the filter dryer and the suspension was mixed overnight at approximately 11° C. The suspension was filtered using positive pressure until a wet cake was obtained. Water saturated MTBE (110 g) was charged to the filter dryer. After 10 minutes, the suspension was filtered with positive pressure until a wet cake was obtained. Water saturated MTBE (261 g) was charged to the filter dryer and the suspension was mixed at approximately 11° C. for 3.5 hours. The suspension was filtered with agitation using positive pressure until a wet cake was obtained. The wet cake was dried with constant agitation at a temperature of approximately 11° C. under humidified nitrogen and positive pressure for two days. Conversion to the upadacitinib Tartrate Hydrate (tetrahydrate) was confirmed by PXRD analysis.

Example 5: Preparation of Freebase Anhydrate Form D

A sample of the Amorphous Freebase of upadacitinib was dissolved in water-free EtOAc at a concentration of 19.6% (w/w). An aliquot comprising approximately 1 mL was transferred to a 4 mL vial equipped with a magnetic stirrer. The vial was sealed with parafilm and mixed at 400 rpm on a magnetic stir plate at around 23° C. for almost 8 weeks. The resulting slurry was filtered and left at ambient conditions for a short period of time prior to characterization. Conversion to Freebase Anhydrate Form D was confirmed by PXRD analysis.

Example 6: Microscopy/Crystal Morphology

The solid state forms of upadacitinib were evaluated by microscopy. Samples were examined by microscopic visual examination using a polarizing microscope (model Eclipse E-600 POL, Nikon Corp., Garden City, N.Y.). A color video camera was used to record digital images (model DXC 390, Fryer Co., Inc., Huntley, Ill.). Images were captured using MetaMorph Imaging System (version 4.6R8, Universal Imaging Corporation, Downingtown, Pa.). Observations regarding the crystal morphology of the samples are reported in Table 14 below. Those of skill in the art will recognize that variation in crystal shape and size may be observed depending upon the specific crystallization conditions employed. The solvation states and PXRD profiles reported in Table 14 correspond to the information presented in the figures and subsequent examples of this application.

Example 7: PXRD Analysis

The solid state forms of upadacitinib listed in Table 14 were analyzed by X-ray powder diffraction (“PXRD”). The PXRD data were collected with a G3000 diffractometer (Inel Corp., Artenay, France) equipped with a curved position sensitive detector and parallel beam optics. The diffractometer was operated with a copper anode tube (1.5 kW fine focus) at 40 kV and 30 mA. An incident beam germanium monochromator provided monochromatic Kα1 radiation λ=1.540562 Å). The diffractometer was calibrated using the attenuated direct beam at one-degree intervals. Calibration was checked using a silicon powder line position reference standard (NIST 640c). Samples were prepared by spreading the sample powder in a thin layer on an aluminum sample holder and gently leveling with a glass microscope slide. The instrument was computer controlled using the Symphonix software (Inel Corp., Artenay, France) and the data was analyzed using the Jade software (version 6.5, Materials Data, Inc., Livermore, Calif.). The aluminum sample holder was mounted on the rotating sample holder of the G3000 diffractometer and the diffraction data collected at ambient conditions.

Tables 15-A through 15-E set out the significant parameters of the main peaks in terms of 2Θ values and intensities for the crystalline forms analyzed. It is known in the art that an X-ray powder diffraction pattern may be obtained which has one or more measurement errors depending on measurement conditions (such as equipment, sample preparation or machine used). In particular, it is generally known that intensities in an X-ray powder diffraction pattern may fluctuate depending on measurement conditions and sample preparation. For example, persons skilled in the art of X-ray powder diffraction will realize that the relative intensities of peaks may vary according to the orientation of the sample under testing and on the type and setting of the instrument used. The skilled person also will realize that the position of reflections can be affected by the precise height at which the sample sits in the diffractometer and the zero calibration of the diffractometer. The surface planarity of the sample also may have an effect on the results. A person skilled in the art will appreciate that the diffraction pattern data presented below is not to be construed as absolute and any crystalline form that provides a power diffraction pattern substantially identical to those disclosed below fall within the scope of the present disclosure (for further information see Jenkins, R & Snyder, R. L. ‘Introduction to X-Ray Powder Diffractometry’, John Wiley & Sons, 1996).

Example 8: Clinical Study for Crohn's Disease

This trial was a multicenter, randomized, double-blind placebo-controlled study of upadacitinib for the induction of symptomatic and endoscopic remission in patient with moderately to severely active Crohn's disease who have inadequately responded to or are intolerant to immunosuppressants or anti-TNF therapy.

The trial consisted of a screening period of up to 30 days, a 16 week double blind induction period, re-randomization at week 16, a 36 week double blind and open label phase and a 30 day follow up period.

Approximately 220 patients with moderately to severely active Crohn's disease—defined for purposes of this study as having 1) Simplified Endoscopic Score for CD (SES-CD)≥6, (or SES-CD≥4 for patients with disease limited to the ileum), 2) a CDAI≥220 and ≤450, and 3) an average daily liquid/soft stool frequency (SF)≥2.5 or an average daily abdominal pain (AP) score ≥2.0)—were randomized in a 1:1:1:1:1:1 ratio to one of the schematics of the overall study design shown in FIG. 1 .

-   -   1. Group 1: upadacitinib 3 mg BID capsules (IR)     -   2. Group 2: upadacitinib 6 mg BID capsules (IR)     -   3. Group 3: upadacitinib 12 mg BID capsules (IR)     -   4. Group 4: upadacitinib 24 mg BID capsules (IR)     -   5. Group 5: upadacitinib 24 mg QD dose (IR) (two 12 mg capsules         administered simultaneously)     -   6. Group 6: Placebo

The 16 week induction period began at the BL visit (week 0) and ended at the week 16 visit. The randomization at BL was stratified by endoscopic disease severity (SES-CD<15 and ≥15). Safety and efficacy evaluations were performed through the end of the study. The end of the study was defined as the date the last patient completed the last follow up visit.

At week 16, patients who had completed the induction period were re-randomized to one of four double-blinded doses of upadacitinib: 3 mg BID, 6 mg BID, 12 mg BID, or 24 mg QD (patients administered two 12 mg capsules simultaneously). The re-randomization was stratified by dose received during the first 16 weeks and overall response (responder versus non-responder) at week 16.

Each treatment group received the corresponding dose of upadacitinib or placebo orally twice daily. Patients receiving the 24 mg QD dose were administered two 12 mg capsules simultaneously orally once daily. At week 12 and week 16, patients were evaluated for clinical remission (average daily SF≤1.5 and not worse than baseline and average daily AP≤1.0 and not worse than baseline). Patients were randomly assigned (1:1) to have an endoscopy at either week 12 or at week 16, and were evaluated for endoscopic remission (SES-CD≤4 and at least a two point reduction in SES-CD versus BL and no subscore >1 in any individual variable used to calculate SES-CD) at week 12 or week 16.

The central reader endoscopic score was used for calculating the endoscopic response for the evaluation of the efficacy endpoints. However, for stratification at the time of re-randomization, the endoscopic score at BL from central reader and the endoscopic score at week 12 or week 16 from site local reader were used in order to determine response status.

The co-primary endpoints for efficacy were:

-   -   endoscopic remission at week 12 or 16     -   clinical remission at week 16

Secondary endpoints to measure efficacy included:

-   -   CDAI<150 at week 16     -   decrease in CDAI of ≥70 points from BL at week 16     -   clinical remission at week 12     -   remission at week 16 (endoscopic remission at week 12 or 16 and         clinical remission at week 16)     -   response at week 16 (endoscopic response at week 12 or 16 and         clinical response at week 16)     -   endoscopic response at week 12 or 16     -   clinical response at week 16     -   whether a subject with an average daily SF≥2.5 and an average         daily AP score ≥2.0 at BL achieves clinical remission at week 16     -   whether a subject taking corticosteroids at BL who discontinues         corticosteroid use achieves CDAI<150 at week 16     -   whether a subject taking corticosteroids at BL who discontinues         corticosteroid use achieves endoscopic remission at week 12 or         week 16 and clinical remission at week 16     -   whether a subject taking corticosteroids at BL who discontinues         corticosteroid use achieves clinical remission at week 16     -   whether a subject taking corticosteroids at BL who discontinues         corticosteroid use achieves endoscopic remission at week 12 or         week 16     -   change from BL in fecal calprotectin level at week 16     -   change from BL in hs-CRP (high sensitivity C-reactive protein)         at week 16     -   change in the Inflammatory Bowel Disease Questionnaire (IBDQ)         from BL at week 16     -   whether a subject with isolated ileal Crohn's Disease achieves         remission at week 16     -   whether a subject achieves remission at week 52     -   whether a subject achieves endoscopic remission at week 52     -   whether a subject achieves clinical remission at week 52     -   whether a subject achieves response at week 52     -   endoscopic response at week 52     -   clinical response at week 52     -   whether a subject taking corticosteroids at BL who discontinued         corticosteroid use achieves CDAI<150 at week 52     -   whether a subject taking corticosteroids at BL who discontinued         corticosteroid use achieves remission at week 52     -   whether a subject taking corticosteroids at BL who discontinued         corticosteroid use achieves clinical remission at week 52     -   whether a subject taking corticosteroids at BL who discontinued         corticosteroid use achieves endoscopic remission at week 52     -   CDAI<150 at week 52     -   decrease in CDAI≥70 points from BL at week 52     -   change from BL in fecal calprotectin level at week 52     -   change from BL in hs-CRP at week 52     -   change in IBDQ from BL at week 52     -   whether subject with isolated ileal Crohn's Disease achieves         remission at week 52     -   change in extra-intestinal manifestations (EIMS) from BL at week         52         Methods

The study comprised two treatment periods: a 16 week double-blind induction period and a 36 week double-blind extension phase. In the induction period, patients with a diagnosis of ileal, colonic, or ileocolonic Crohn's disease for ≥3 months prior to BL and confirmed by endoscopy during the screening period, a CDAI≥220 and ≤450, and who have inadequately responded to or experienced intolerance to previous treatment with an anti-TNF agent (e.g. infliximab, adalimumab or certolizumab pegol), were assigned to receive one of the following doses of upadacitinib 3 mg BID, 6 mg BID, 12 mg BID, 24 mg BID or 24 mg QD or placebo. The co-primary endpoints were endoscopic remission at week 12 or week 16 and clinical remission at week 16. Secondary endpoints included CDAI<150 at week 16 and endoscopic response at week 12 or 16.

Eligible patients were aged 18 to 75 years. They had a diagnosis of CD for at least three months and at screening had moderate-to-severe CD, defined as a 1) SES-CD≥6 (or ≥4 for patients with disease limited to the ileum), 2) a CDAI of 220-450, and 3) an average daily liquid/soft SF score ≥2.5 or an average daily AP score ≥2.0. Patients had inadequately responded to or experienced intolerance to previous treatment with an anti-TNF agent. Patients with a current diagnosis of ulcerative colitis, collagenous colitis or indeterminate colitis as well as patients with previous exposure to a JAK inhibitor were excluded.

Baseline demographics and disease characteristics were similar between study arms. In total there were 95 males and 125 females, with a mean age of 42.5 years and mean CDAI of 302.83; 96.0% percent of patients had previously been exposed to ≥1 TNF antagonists. At week 12/16, endoscopic remission was achieved by 10.3%, 8.1%, 8.3%, 22.2% and 14.3% of patients treated with 3 mg BID, 6 mg BID, 12 mg BID, 24 mg BID and 24 mg QD, respectively, of upadacitinib, compared with 0% of patients treated with placebo (p=0.056, p=0.108, p=0.099, p=0.004, p=0.025, respectively, see Table 17). At week 16, clinical remission was achieved by 12.8%, 27.0%, 11.1%, 22.2% and 14.3% of patients treated with 3 mg BID, 6 mg BID, 12 mg BID, 24 mg BID and 24 mg QD, respectively, of upadacitinib, compared 10.8% of patients treated with placebo (p=0.740, p=0.082, p=0.952, p=0.205, p=0.607, respectively, see Table 17). Clinical remission was observed in some patients as early as week 12. The percentage of patients achieving clinical remission at week 12 is shown in FIG. 6A (patients not on baseline steroids) and FIG. 6B (patients who were on steroids at baseline, and underwent mandatory taper of steroid dose starting at week 2). The steroid taper consisted of a weekly decrease by 5 mg/day of prednisone (or equivalent) for doses >10/mg/day of prednisone (or equivalent) until a 10 mg/day (or equivalent) dose was reached, then a weekly decrease by 2.5 mg/day (or equivalent) until discontinuation. Upadacitinib was shown to induce clinical remission as early as week 12.

Clinical response was achieved at week 16 by 43.6%, 56.8%, 47.2%, 61.1% and 48.6% of patients treated with 3 mg BID, 6 mg BID, 12 mg BID, 24 mg BID and 24 mg QD, respectively, of upadacitinib, compared with 32.4% of patients treated with placebo. Endoscopic response was achieved at week 12 or week 16 by 23.1%, 43.2%, 38.9%, 50.0% and 48.6% of patients treated with 3 mg BID, 6 mg BID, 12 mg BID, 24 mg BID and 24 mg QD, respectively, of upadacitinib, compared with 13.5% of patients treated with placebo.

Clinical remission and endoscopic remission was achieved at week 16 by 2.6%, 5.4%, 2.8%, 8.3% and 5.7% of patients treated with 3 mg BID, 6 mg BID, 12 mg BID, 24 mg BID and 24 mg QD, respectively, of upadacitinib, compared with 0% of patients treated with placebo. Clinical and endoscopic response was achieved at week 16 by 15.4%, 32.4%, 27.8%, 38.9% and 34.3% of patients treated with 3 mg BID, 6 mg BID, 12 mg BID, 24 mg BID and 24 mg QD, respectively, of upadacitinib, compared with 2.7% of patients treated with placebo. Results are shown in Table 18.

Clinical remission was achieved at week 12 by 10.3%, 29.7%, 13.9%, 25.0% and 8.6% of patients treated with 3 mg BID, 6 mg BID, 12 mg BID, 24 mg BID and 24 mg QD, respectively, of upadacitinib, compared with 10.8% of patients treated with placebo. Clinical response was achieved at week 12 by 53.8%, 64.9%, 52.8%, 55.6% and 51.4% of patients treated with 3 mg BID, 6 mg BID, 12 mg BID, 24 mg BID and 24 mg QD, respectively, of upadacitinib, compared with 35.1% of patients treated with placebo.

Modified clinical remission was achieved at week 16 by 15.8%, 30.3%, 26.5%, 36.7%, and 18.8% of patients treated with 3 mg BID, 6 mg BID, 12 mg BID, 24 mg BID and 24 mg QD, respectively, of upadacitinib, compared with 12.1% of patients treated with placebo. Results are shown in Table 19.

Endoscopic improvement was achieved at week 12 or week 16 by 12.8%, 18.9%, 27.8%, 36.1%, and 25.7% of patients treated with 3 mg BID, 6 mg BID, 12 mg BID, 24 mg BID and 24 mg QD, respectively, of upadacitinib, compared with 3.0% of patients treated with placebo. Results are shown in Table 19. Of the patients who were evaluated for endoscopic improvement at week 12, 10.5%, 13.3%, 25%, 33.3%, and 12.5% of patients treated with 3 mg BID, 6 mg BID, 12 mg BID, 24 mg BID and 24 mg QD, respectively, of upadacitinib, achieved endoscopic improvement by week 12, compared with 0% of patients treated with placebo.

This study included refractory patients with moderately to severely active Crohn's disease, who have had Crohn's disease for more than ten years and who have failed several treatments, including biologic treatments. Table 16 above shows the number of patients in the study that received prior anti-TNF treatment, treatment with prior non-anti-TNF biologics, treatment with vedolilzumab, and who were being treated with steroids at baseline, as well as the average duration of Crohn's disease at baseline. Typically, because refractory patients are treated with different therapeutics, the efficacy of each treatment progressively decreases. Surprisingly, however, the current study demonstrated that when treated with upadacitinib, the refractory patients showed unprecedented efficacy. The results for refractory patients in the study are shown in FIG. 9 .

As shown by FIG. 9 , refractory patients treated with upadacitinib achieved clinical remission and endoscopic response at unprecedented rates. At week 16, 15.8% of refractory patients treated with 3 mg BID of upadacitinib achieved clinical remission. At week 16, 30.3% of refractory patients treated with 6 mg BID of upadacitinib achieved clinical remission. At week 16, 26.5% of refractory patients treated with 12 mg BID of upadacitinib achieved clinical remission. At week 16, 36.7% of refractory patients treated with 24 mg QD (two 12 mg BID doses given simultaneously) achieved clinical remission.

In addition, as also shown in FIG. 9 , a surprising proportion of refractory patients treated with upadacitinib achieved endoscopic remission at 12 or 16 weeks. 13.2% of refractory patients treated with 3 mg BID of upadacitinib achieved endoscopic remission at 12 or 16 weeks. 21.2% of refractory patients treated with 6 mg BID of upadacitinib achieved endoscopic remission at 12 or 16 weeks. 29.4% of refractory patients treated with 2 mg BID of upadacitinib achieved endoscopic remission at 12 or 16 weeks. 33.3% of refractory patients treated with 24 mg QD (two 12 mg doses given simultaneously) of upadacitinib achieved endoscopic remission at 12 or 16 weeks.

The relationship between upadacitinib plasma concentrations and the primary endpoints and certain secondary and additional endpoints is set forth in FIGS. 3A-3I. Exposure-response relationships were observed for clinical response, clinical remission, CDAI remission (CDAI<150), endoscopic response, endoscopic improvement, and endoscopic remission.

Safety

The incident of adverse events was numerically higher (˜3-13%) in upadacitinib dose groups, compared to placebo, with no clear dose-relationship. Severe adverse events and treatment discontinuations due to adverse events were lower/comparable across all upadacitinib dose groups compared to placebo except in the 12 mg BID dose group. There were no treatment emergent deaths in the study. Overall, the incidence of adverse events of special interest were low (except for infections) and similar across all treatment groups. Infections were increased in all upadacitinib BID dose groups compared to placebo. Two adjudicated major adverse cardiac events (MACE) were observed in the 12 mg BID dose group (two had an acute myocardial infarction).

The relationship between upadacitinib plasma concentration and the change from baseline in hemoglobin levels, anemia, LDL and HDL cholesterol, neutropenia, lymphopenia, and natural killer (NK) cell levels was determined, and the results shown in FIGS. 5A-5H. Exposure-response relationships for effects of upadacitinib on NK cells, neutrophils, LDL and HDL cholesterol in Crohn's patients were generally consistent with those previously observed in RA patients. Compared to RA patients (data not shown), subjects with Crohn's had lower decreases in hemoglobin (FIG. 5A).

Example 9: Model Predicted Efficacy for Once-Daily Doses

Based on the data obtained in Example 8 for administration of an immediate release (IR) formulation of upadacitinib BID, the exposure-response relationships (simulating for 200 patients/arm) for 15 mg, 30 mg, and 45 mg modified-release QD doses of upadacitinib, for placebo, for 6 mg, 12 mg, 18 mg, and 24 mg IR BID doses of upadacitinib, and for 24 mg IR QD doses of upadacitinib was predicted. The full time-course for the different clinical endpoints was analyzed using Markov analyses. The Marko models allowed transition between response, no response, and dropouts. The models evaluated C_(p), C_(ave), C_(min), and C_(max) as predictors for drug efficacy. The different endoscopic endpoints at Week 12/16 were analyzed using logistic regression analyses. Then, the models were used to simulate clinical response, clinical remission, CDAI<150, endoscopic response, endoscopic improvement and endoscopic remission at Weeks 12 and 16 (when applicable) for different dose regimens for both the immediate and modified release formulation by back transforming exposures to doses. The results are set forth in FIGS. 4A-4F.

This modelling suggests 1-3% improvements in clinical parameters between doses with the MR formulation.

Example 10: Clinical Study for Crohn's Disease: Long-term Efficacy and Safety of Upadacitinib in Moderate to Severe Crohn's Disease

In Example 10, the extension phase of the Example 8 clinical study was studied and discussed. The trial was a multicenter, randomized, double-blind placebo-controlled study of upadacitinib for the induction of symptomatic and endoscopic remission in patient with moderately to severely active Crohn's disease who have inadequately responded to or are intolerant to immunosuppressants or anti-TNF therapy.

The trial consisted of a screening period of up to 30 days, a 16 week double blind induction period, re-randomization at week 16, a 36 week double blind and open label phase and a 30 day follow up period.

Approximately 220 patients with moderately to severely active Crohn's disease—defined for purposes of this study as having 1) Simplified Endoscopic Score for CD (SES-CD)≥6, (or SES-CD≥4 for patients with disease limited to the ileum), 2) a CDAI≥220 and ≤450, and 3) an average daily liquid/soft stool frequency (SF)≥2.5 or an average daily abdominal pain (AP) score ≥2.0)—were randomized in a 1:1:1:1:1:1 ratio to one of the schematics of the overall study design shown in FIG. 1 .

-   -   1. Group 1: upadacitinib 3 mg BID capsules (IR)     -   2. Group 2: upadacitinib 6 mg BID capsules (IR)     -   3. Group 3: upadacitinib 12 mg BID capsules (IR)     -   4. Group 4: upadacitinib 24 mg BID capsules (IR)     -   5. Group 5: upadacitinib 24 mg QD dose (IR) (two 12 mg capsules         administered simultaneously)

6. Group 6: Placebo

The 16 week induction period began at the BL visit (week 0) and ended at the week 16 visit. The randomization at BL was stratified by endoscopic disease severity (SES-CD<15 and ≥15). Safety and efficacy evaluations were performed through the end of the study. The end of the study was defined as the date the last patient completed the last follow up visit.

At week 16, patients who completed the 16-week induction phases were re-randomised 1:1:1 to double-blind upadacitinib at 3 mg twice daily (BID), 12 mg BID or 24 mg daily (QD) for 36 weeks. A protocol amendment stopped enrolment in the 24 mg QD arm and initiated a 6 mg BID arm. A total of 180 patients were re-randomised to one of four double-blinded doses of upadacitinib:

-   -   1. Group 1: upadacitinib 3 mg BID capsules (IR)     -   2. Group 2: upadacitinib 6 mg BID capsules (IR)     -   3. Group 3: upadacitinib 12 mg BID capsules (IR)     -   4. Group 4: upadacitinib 24 mg QD dose (IR) (two 12 mg capsules         administered simultaneously)

The re-randomization was stratified by dose received during the first 16 weeks and overall response (responder versus non-responder) at week 16.

Each treatment group received the corresponding dose of upadacitinib orally once or twice daily. Patients receiving the 24 mg QD dose were administered two 12 mg capsules simultaneously orally once daily. At week 52, patients were evaluated for clinical remission (average daily SF≤1.5 and not worse than baseline and average daily AP≤1.0 and not worse than baseline), CDAI<150, modified clinical remission (SF≤2.8 and AP≤1.0, both not worse than BL in patients with SF≥4, AP≥2.0 at BL), clinical response (≥30% decrease in SF or AP, both not worse than BL), endoscopic remission (SES-CD≤4 and ≥2-point reduction from BL and no subscore >1), endoscopic response (SES-CD reduction >50% from BL or endoscopic remission) and change from BL in C-reactive protein (CRP) and faecal calprotectin (FC).

The co-primary endpoints for efficacy were the same as the endpoints in Example 8 study.

Methods

The study comprised two treatment periods: a 16 week double-blind induction period and a 36 week double-blind extension phase. In the induction period, patients with a diagnosis of ileal, colonic, or ileocolonic Crohn's disease for ≥3 months prior to BL and confirmed by endoscopy during the screening period, a CDAI≥220 and ≤450, and who have inadequately responded to or experienced intolerance to previous treatment with an anti-TNF agent (e.g. infliximab, adalimumab or certolizumab pegol), were assigned to receive one of the following doses of upadacitinib 3 mg BID, 6 mg BID, 12 mg BID, 24 mg BID or 24 mg QD or placebo. The co-primary endpoints were endoscopic remission at week 12 or week 16 and clinical remission at week 16. Secondary endpoints included CDAI<150 at week 16 and endoscopic response at week 12 or 16. In the extension phase, patients who completed the 16-week induction phases were re-randomised 1:1:1 to double-blind upadacitinib at 3 mg twice daily (BID), 12 mg BID or 24 mg daily (QD) for 36 weeks. A protocol amendment stopped enrolment in the 24 mg QD arm and initiated a 6 mg BID arm. Clinical remission (average daily stool frequency [SF]≤1.5 and abdominal pain score [AP] ≤1.0, both not worse than Baseline [BL]), CDAI<150, modified clinical remission (SF≤2.8 and AP≤1.0, both not worse than BL in patients with SF≥4, AP≥2.0 at BL), clinical response (≥30% decrease in SF or AP, both not worse than BL), endoscopic remission (SES-CD≤4 and ≥2-point reduction from BL and no subscore >1), endoscopic response (SES-CD reduction >50% from BL or endoscopic remission) and change from BL in C-reactive protein (CRP) and faecal calprotectin (FC) were analysed at week 52 in patients with either both clinical and endoscopic response or clinical response at week 16. Endoscopies were evaluated at BL, 12/16 and 52 weeks by a central reader. Patients who received open label upadacitinib (escape) or prematurely discontinued prior to week 52 were considered non-responders (non-responder imputation). Adverse events were collected throughout the study up to 30 days after the last upadacitinib dose.

Eligibility, key demographics and BL characteristics of the patients were essentially the the same as those in Example 8 study.

Baseline demographics and disease characteristics were similar between study arms. At week 52, endoscopic remission was achieved by 16%, 21%, 24%, and 26% of patients treated with 3 mg BID, 6 mg BID, 12 mg BID, and 24 mg QD, respectively, of upadacitinib. At week 52, clinical remission was achieved by 25%, 29%, 41%, and 32% of patients treated with 3 mg BID, 6 mg BID, 12 mg BID, and 24 mg QD, respectively, of upadacitinib. Results are shown in Table 21.

Clinical response was achieved at week 52 by 50%, 71%, 62%, and 42% of patients treated with 3 mg BID, 6 mg BID, 12 mg BID, and 24 mg QD, respectively, of upadacitinib Enhanced clinical response was achieved at week 52 by 47%, 71%, 62%, and 42% of patients treated with 3 mg BID, 6 mg BID, 12 mg BID and 24 mg QD, respectively, of upadacitinib. Results are shown in Table 21.

Among subjects who achieved clinical response and endoscopic response at week 16, endoscopic response was achieved at week 52 by 50.0%, 50.0%, 68.8%, and 30.0% of patients treated with 3 mg BID, 6 mg BID, 12 mg BID, and 24 mg QD, respectively, of upadacitinib. Among subjects who achieved clinical response at week 16, endoscopic response was achieved at week 52 by 34.4%, 35.7%, 44.8%, and 36.8% of patients treated with 3 mg BID, 6 mg BID, 12 mg BID, and 24 mg QD, respectively, of upadacitinib. Results are shown in Table 21. Among subjects who achieved clinical response and endoscopic response at week 16, endoscopic response was achieved at week 52 by 34.4, 35.7, 44.8 and 36.8% of patients treated with 3 mg BID, 6 mg BID, 12 mg BID and 24 mg QD, respectively.

Among subjects who achieved clinical response and endoscopic response at week 16, modified clinical remission was achieved at week 52 by 41.2%, 62.5%, 73.3%, and 40.0% of patients treated with 3 mg BID, 6 mg BID, 12 mg BID, and 24 mg QD, respectively, of upadacitinib. Among subjects who achieved clinical response at week 16, modified clinical remission was achieved at week 52 by 28.6%, 42.9%, 51.9%, and 38.9% of patients treated with 3 mg BID, 6 mg BID, 12 mg BID, and 24 mg QD, respectively, of upadacitinib. Results are shown in Table 21.

Safety

The incident of adverse events (AEs) was numerically higher with upadacitinib 3 and 12 mg BID (45 [75.0%] and 43 [72.9%]) than that with 6 mg BID and 24 mg QD (14 [60.9%] and 23 [63.9%]), respectively. Serious AEs were numerically higher with 3 mg BID and infections with 3 and 12 mg BID than that in the other arms. Two malignancies occurred with 12 mg BID.

Conclusion

Dose-dependent improvements in clinical and endoscopic outcomes and markers of inflammation were observed with 36-week upadacitinib treatment in patients who responded to a 16-week induction regimen. The overall safety profile of upadacitinib is consistent with other studies in rheumatoid arthritis.

Example 11: Clinical Study for Crohn's Disease: Rapidity of Clinical and Laboratory Improvements Following Upadacitinib Induction Treatment

This analysis evaluates the rapidity of clinical remission, clinical response, and changes in markers of inflammation during the induction phase of the clinical study discussed in Example 8.

Methods

Adult patients with Crohn's Disease Activity Index (CDAI) 220-450, average daily liquid/very soft stool frequency (SF)≥2.5 or daily abdominal pain score (AP)≥2.0, and Simplified Endoscopic Score for CD (SES-CD)≥6 [or ≥4 for those with isolated ileal disease), were randomized to double-blind therapy with placebo (PBO) or immediate release formulation of upadacitinib at 3, 6, 12, 24 mg twice daily (BID) or 24 mg once daily (QD) for 16 weeks. Patients were randomized at baseline for follow-up ileocolonoscopy at either Week 12 or 16. Proportion of patients with modified clinical remission and enhanced clinical response, both defined in Figure, mean change from baseline in C-reactive protein (CRP) and faecal calprotectin (FC) were assessed over time in all patients unless otherwise mentioned. Comparisons between each upadacitinib dose with PBO was tested by Cochran-Mantel-Haenszel test stratified by SES-CD at BL. Non-responder imputation was applied to patients who received open-label upadacitinib or prematurely discontinued prior to Week 16 or initiated corticosteroids or had dose increase higher than baseline.

Results

Baseline demographics and disease characteristics were similar between study arms. A total of 220 patients were enrolled (mean age 40.7±12.9 years, CDAI 302.7±63.4, disease duration 13.2±10.0 years). Overall, patients receiving upadacitinib achieved modified clinical remission as early as week 4 and enhanced clinical response at week 8. Over time, there were sustained clinical improvements in several upadacitinib dosage groups for up to 16 weeks (FIGS. 10A-10E and FIGS. 11A-11E). Mean C-reactive protein (CRP) levels significantly decreased in all upadacitinib doses at week 4 and were sustained for up to 16 weeks in the 12 and 24 mg BID and 24 mg QD arms (FIG. 12 ). Statistically significant decrease in mean faecal calprotectin (FC) from baseline was observed with upadacitinib at 12 and 24 mg BID at week 4 and 24 mg BID at week 16.

Conclusions

Early and significant effects of upadacitinib in clinical parameters were demonstrated in a refractory patient population with active Crohn's disease, concurrent with rapid and sustainable decrease in the markers of inflammation hsCRP and faecal calprotectin.

Example 12: Clinical Study for Ulcerative Colitis

This trial is a multicenter, randomized, double-blind placebo-controlled study of upadacitinib for the induction and maintenance of clinical remission (using the Mayo Scoring System for Assessment of Ulcerative Colitis Activity, excluding Physician's Global Assessment [i.e., Adapted Mayo score]) in patients with moderately to severely active ulcerative colitis.

The trial consists of a screening period of up to 35 days, an 8 week double blind induction period (Substudy 1), a second 8 week double blind and open label induction period (Substudy 2), re-randomization at week 8, a 44 week double blind and open label maintenance phase (Substudy 3), and a 30 day follow up period.

Approximately 250 patients with moderately to severely active ulcerative colitis are randomized in a 1:1:1:1:1 ratio for Substudy 1 to one of the treatment arms of the overall study design shown in FIG. 13 .

-   -   1. Group 1: upadacitinib 7.5 mg QD MR capsules     -   2. Group 2: upadacitinib 15 mg QD MRcapsules     -   3. Group 3: upadacitinib 30 mg QD MR capsules     -   4. Group 4: upadacitinib 45 mg QD MR capsules     -   5. Group 5: Placebo QD dose

The first 8 week induction period begins at the BL visit (week 0) and ends at the week 8 visit. Once the 250 randomized patients have completed an 8 week induction, an analysis of efficacy and safety of upadacitinib versus placebo will be performed. Based on this analysis, one induction dose of upadacitinib (Dose A) will be identified for further evaluation in Substudy 2. During the analysis period, approximately 100 additional subjects will continue to be randomized into Groups 3 and 4 of Substudy 1 to receive either 30 mg QD or 45 mg QD treatment (50 patients per dose group).

Substudy 2 consists of two parts. In Part 1, approximately 375 patients with moderately to severely active ulcerative colitis are randomized in a 2:1 ratio to one of the double-blinded induction treatment arms as shown in FIG. 13 : upadacitinib Dose A mg QD or placebo QD. Dose A is the dose determined in Substudy 1 for further evaluation. Part 2 of Substudy 2 is open label. Approximately 330 subjects will be enrolled in Part 2 of Substudy 2 to receive open-label upadacitinib Dose A QD. This second 8 week induction period begins at the BL visit (week 0) and ends at the week 8 visit.

Approximately 450 patients who received the 15, 30 or 45 mg QD of upadacitinib in Substudy 1 and those who received the selected induction dose in Substudy 2 and who also achieved a clinical response (i.e., a decrease from baseline in the Adapted Mayo score ≥2 points and ≥30% from baseline accompanied by a decrease in RBS≥1 or an absolute RBS≤1) will be re-randomized in the maintenance portion of the study (Substudy 3). This period will begin at the baseline visit (Week 8 of Substudy 1 or Substudy 2) and will end at the Week 44 visit. The treatment assignment in Substudy 3 will depend on the treatment received in Substudies 1 and 2, as follows:

Placebo: continue placebo

7.5 mg QD upadacitinib: continue 7.5 mg QD upadacitinib

15 mg QD upadacitinib: randomized 1:1 to receive either upadacitinib 15 mg QD or matching placebo

30 mg QD or 45 mg QD upadacitinib: randomized 1:1:1 to receive either upadacitinib 15 mg QD, upadacitinib 30 mg QD, or matching placebo.

During Substudy 3, subjects who meet the criteria for loss of response after at least 4 weeks of follow up will have the option receive open label upadacitinib. Loss of response is defined as follows: a subject who presents with an stool frequency subscore and RBS score at least 1 point greater than the end-of-induction value (Week 8 of Substudy 1 or 2) on two consecutive visits at least 14 days apart. The schematics of the overall study design are shown in FIG. 13 .

The primary endpoints for efficacy for Substudy 1 and Substudy 2 are the proportion of patients who achieve clinical remission per Adapted Mayo score (defined as stool frequency subscore ≤1, rectal bleeding subscore of 0, and endoscopic subscore ≤1) at week 8. The primary efficacy endpoint for Substudy 3 is the proportion of patients who achieve clinical remission per Adapted Mayo score at week 44. Secondary efficacy endpoints for both Substudy 1 and Substudy 2 are:

-   -   endoscopic improvement (defined as endoscopic subscore ≤1)     -   achieving Full Mayo score ≤2 with no subscore >1) at week 8     -   Clinical response (i.e., decrease from baseline in the Adapted         Mayo score ≥2 points and ≥30% from baseline, plus a decrease in         rectal bleeding subscore (RBS)≥1 or an absolute RBS≤1) at week 8     -   decrease from baseline in the Partial Mayo score ≥2 points and         ≥30% from baseline plus a decrease in rectal bleeding subscore         (RBS)≥1 or an absolute RBS≤1) at week 2     -   Change in Full Mayo score from Baseline to Week 8     -   Endoscopic remission (defined as endoscopic subscore of 0) at         Week 8     -   Histologic improvement (defined as decrease from baseline in         Geboes score) at week 8

Secondary efficacy endpoints for Substudy 3 maintenance are:

-   -   Endoscopic improvement at week 44     -   Full Mayo score ≤2 with no subscore >1) at week 44     -   Subjects who discontinued corticosteroid use and achieved         clinical remission per Adapted Mayo score at week 44     -   Subjects who maintain clinical remission at Week 44 among         subjects who achieved clinical remission per Adapted Mayo score         in Substudy 1 or 2     -   Subjects who are taking corticosteroids at baseline and are         corticosteroid-free at week 44     -   Subjects with endoscopic improvement at week 44 among subjects         who achieved clinical remission in Substudy 1 or 2     -   Subjects achieving clinical response (i.e., decrease from         baseline in the Adapted Mayo score ≥2 points and ≥30% from         baseline accompanied by a decrease in RBS≥1 or an absolute         RBS≤1) at week 44     -   Subjects with endoscopic remission at week 44     -   Subjects who achieved histologic improvement at week 44         Methods

The study comprised three treatment periods: Substudy 1 comprising an 8 week double-blind induction period; Substudy 2 comprising two parts: Part 1 is an 8 week double-blind induction period and Part 2 is an 8 week open-label option of the substudy; Substudy 3 evaluates patients from Substudy 1 and Substudy 2 who achieved clinical response.

Eligible patients are aged 18 to 75 years. They have a diagnosis of ulcerative colitis for 90 days or greater prior to baseline, confirmed by colonoscopy during the screening period, with exclusion of current infection, colonic dysplasia and/or malignancy. Patients have active ulcerative colitis with an Adapted Mayo score of 5 to 9 points and an endoscopic subscore of 2 to 3 at baseline.

Examples 13-16: Modified Release Tablets

Modified release tablets containing either 7.5 mg (Example 13) 15 mg (Example 14), 30 mg (Example 15), or 45 mg (Example 16) of upadacitinib were prepared using a wet granulation process.

Upadacitinib (hemi-hydrate), microcrystalline cellulose (MCC), and hydroxypropyl methylcellulose (HPMC) were added to a granulator and mixed. Water was sprayed to granulate. The granulated material was then dried and milled using a comill fitted with a 610 micron screen to form a granulate composition containing 25% drug load. The granulate composition is summarized in Table 22.

TABLE 22 Granulate Composition (25% Drug Load) Amount in Granulation Component Function Composition (%) Upadacitinib freebase (hemi- Active 25.0% hydrate)¹ Microcrystalline cellulose Filler 67.0% (Avicel ® PH 101) HPMC (Hypromellose 2208) Release control 8.0% polymer ¹Upadacitinib used in Examples 13-16 was a hemi-hydrate (Freebase Hydrate Form C, as described herein and in U.S. Patent Application No. 15/295,561). As used herein, the amount of upadacitinib present in the Examples 13-16 formulations refers to the amount of upadacitinib freebase equivalent provided by the hemi-hydrate.

The granulation composition was combined with the remaining formulation components other than magnesium stearate, and sieved using a comill fitted with a 1397 micron screen, followed by blending. The magnesium stearate was then added to the bin and blended. The lubricated granulation was compressed into tablets using a rotary tablet press. The tablets were coated using a film coater, which sprayed a solution containing the Opadry® II Yellow film coat and purified water until the desired amount of coating had been applied to the tablets.

The formulations of the tablets are set forth in Table 23.

Example 17: Observed Steady State Exposures for 15 mg Modified Release Tablets and 6 mg Immediate Release Capsules Under Fasting Conditions

The steady state pharmacokinetic profile of a 15 mg once daily modified release (MR) tablet (comprising upadacitinib hemi-hydrate) under fasting conditions was evaluated, and compared to that of a 6 mg immediate release (IR) twice daily (BID) capsule comprising upadacitinib (tartrate tetrahydrate) as the active. The 15 mg MR tablet had the following formulation set forth in Table 24.

The hemi-hydrate provides about 15 mg of upadacitinib freebase equivalent.

The tablet was prepared by first milling the tartaric acid through a Fitz mill Model MSA, fitted with a 1512-0027 screen. The upadacitinib hemi-hydrate, microcrystalline cellulose, mannitol (when present), milled tartaric acid, release control polymer, and colloidal silicone dioxide (when present) were combined and blended. The blend was milled using a Mobil Mill fitted with a 610 or 1397 micron screen. The magnesium stearate was screened through mesh #30 and was then added to the bin and blended. The lubricated granulation was compressed into about 480 mg weight tablets using a rotary tablet press. The tablet was coated using a film coater, which sprayed a solution containing the Opadry® II Yellow film coat and purified water until 14.40 mg of coating had been applied to the tablets.

Healthy human subjects were assigned to one of two regimens under fasting conditions in a randomized, two-period, cross-over study design. Subjects in Regimen K (n=12 at onset; n=11 on Day 7) were administered the 6 mg IR capsule twice daily for seven days under fasting conditions. Subjects in Regimen L (n=12) were administered the 15 mg MR tablet once daily for seven days under fasting conditions. On days one and seven, serial blood samples were collected from each subject prior to the daily dosing and up to 24 hours after dosing. Blood samples were also collected at 48, 72, 96 and 120 hours after initial dosing. Upon collection, the samples were promptly placed in an ice bath, and within 2 hours after sample collection they were centrifuged at about 4° C. The resulting plasma samples were placed in clean polypropylene-tubes and stored in a freezer until analysis. The plasma samples were assayed for upadacitinib using appropriate liquid chromatography mass spectrometry procedures. Pharmacokinetic parameters were estimated using non-compartmental methods, and summary statistics were computed for each parameter by regimen.

The results are summarized in Table 25. The mean plasma concentration of upadacitinib at each time point measured for each of the two regimens is set forth in FIG. 7 .

The relative bioavailability for the once-daily (MR) tablet formulation (Regimen L) relative to the twice daily (IR) capsule formulation (Regimen K) at steady state was also determined based on analysis of the natural logarithms of C_(max), AUC₂₄, C_(min), and C₂₄. The results are summarized in Table 26 below.

TABLE 265 Relative Bioavailability Estimates and 90% Confidence Intervals for 15 mg QD Tablets Relative to 6 mg BID Capsules at Steady State under Fasting Conditions Relative Bioavailability 90% Confidence PK Parameter Point Estimate Interval C_(max) 0.909 0.736-1.122 AUC₂₄ 0.939 0.837-1.053 C_(min) 1.090 0.852-1.395

The ratio of steady-state AUC for the 15 mg QD tablets relative to the 6 mg BID capsules was approximately 1, with the 90% confidence intervals within the equivalence boundaries. The ratio of the steady-state C_(min) was approximately 1 for the 15 mg QD tablet relative to the 6 mg BID capsules.

As can be seen from this data, at steady state under fasting conditions, the 15 mg QD tablets provided equivalent AUC₂₄ and comparable C_(max) and C_(min) relative to the 6 mg BID capsules. The steady state C_(max) was 10% lower for the 15 mg QD tablet compared to the 6 mg BID capsule.

Example 18: Observed Steady State Exposures for 30 mg Modified Release Tablets and 12 mg Immediate Release Capsules Under Fasting Conditions

The steady state pharmacokinetic profile of a 30 mg once daily modified release (MR) tablet (comprising upadacitinib hemi-hydrate) under fasting conditions was evaluated, and compared to that of a 12 mg immediate release (IR) twice daily (BID) capsule comprising upadacitinib (tartrate tetrahydrate) as the active. The 30 mg MR tablet had the following formulation set forth in Table 27.

TABLE 27 30 mg Modified Release Tablet Amount Component Function (mg) (ER8) Upadacitinib (hemi-hydrate)¹ Active 30.7 Microcrystalline cellulose Filler 147.1 (Avicel ® PH 102) Mannitol (Pearlitol ® 100 SD) Filler 52.6 Tartaric acid pH modifier 144.0 HPMC (Hypromellose 2208) Release control polymer 96.0 Colloidal silicon dioxide Glidant 2.4 Magnesium stearate Lubricant 7.2 impalpable powder Uncoated weight of tablet 480.0 Opadry ® II Yellow (PVA Film coat 14.40 based) Total weight of tablet 494.43 ¹Upadacitinib was a hemi-hydrate (Freebase Hydrate Form C, as described in U.S. Patent Application No. 15/295,561). The hemi-hydrate provides about 30 mg of upadacitinib freebase equivalent.

The tablet was prepared by first milling the tartaric acid through a Fitz mill Model MSA, fitted with a 1512-0027 screen. The upadacitinib hemi-hydrate, microcrystalline cellulose, mannitol (when present), milled tartaric acid, release control polymer, and colloidal silicone dioxide (when present) were combined and blended. The blend was milled using a Mobil Mill fitted with a 610 or 1397 micron screen. The magnesium stearate was screened through mesh #30 and was then added to the bin and blended. The lubricated granulation was compressed into about 480 mg weight tablets using a rotary tablet press. The tablet was coated using a film coater, which sprayed a solution containing the Opadry® II Yellow film coat and purified water until 14.40 mg of coating had been applied to the tablets.

Healthy human subjects were assigned to one of two regimens under fasting conditions in a randomized, two-period, cross-over study design. Subjects in Regimen M (n=11) were administered the 12 mg IR capsule twice daily for seven days under fasting conditions. Subjects in Regimen N (n=12 at onset; n=11 at Day 7) were administered the 30 mg MR tablet once daily for seven days under fasting conditions. On days one and seven, serial blood samples were collected from each subject prior to the daily dosing and up to 24 hours after dosing. Blood samples were also collected at 48, 72, 96 and 120 hours after initial dosing. Upon collection, the samples were promptly placed in an ice bath, and within 2 hours after sample collection they were centrifuged at about 4° C. The resulting plasma samples were placed in clean polypropylene-tubes and stored in a freezer until analysis. The plasma samples were assayed for upadacitinib using appropriate liquid chromatography mass spectrometry procedures. Pharmacokinetic parameters were estimated using non-compartmental methods, and summary statistics were computed for each parameter by regimen.

The results are summarized in Table 28. The mean plasma concentration of upadacitinib at each time point measured for each of the two regimens is set forth in FIG. 8 .

The relative bioavailability for a single dose of the once-daily (MR) tablet formulation (Regimen N) relative to the twice daily (IR) capsule formulation (Regimen M) was also determined based on analysis of the natural logarithms of C_(max), AUC₂₄, C_(min), and C₂₄. The results are summarized in Table 29 below.

TABLE 29 Relative Bioavailability Estimates and 90% Confidence Intervals for 30 mg QD Tablets Relative to 12 mg BID Capsules at Steady State under Fasting Conditions Relative Bioavailability 90% Confidence PK Parameter Point Estimate Interval C_(max) 0.900 0.732-1.107 AUC₂₄ 0.974 0.869-1.092 C_(min) 0.874 0.747-1.022

The ratio of steady-state AUC for the 30 mg QD tablets relative to the 12 mg BID capsules was approximately 1, with the 90% confidence intervals within the equivalence boundaries. The steady-state C_(min) for the 30 mg QD tablet was approximately 13% lower than for the 12 mg BID capsules. Outliers with high C_(min) in the 12 mg BID dose may have contributed to this difference.

As can be seen from this data, at steady state under fasting conditions, the 30 mg QD tablets provided equivalent AUC₂₄ and comparable C_(max) and C_(min) relative to the 12 mg BID capsules. The steady state C_(max) was 10% lower for the 30 mg QD tablet compared to the 12 mg BID capsules.

Example 19. Clinical Study for Ulcerative Colitis

This study is a Phase 3, multicenter, randomized, double-blind, placebo-controlled efficacy and safety study to evaluate the efficacy and safety of upadacitinib (ABT-494) in subjects with moderately to severely active ulcerative colitis.

Objective

The primary objective of this study is to evaluate the efficacy and safety of upadacitinib 45 mg once daily (QD) compared to placebo in inducing clinical remission (per Adapted Mayo score) in subjects with moderately to severely active ulcerative colitis (UC). Particularly, the primary objective is to evaluate the efficacy and safety of upadacitinib 45 mg once daily (QD) compared to placebo in inducing clinical remission (per Adapted Mayo score) in subjects with moderately to severely active UC who have demonstrated inadequate response, loss of response, or intolerance to oral aminosalicylates, immunosuppressants, corticosteroids, and/or biologic therapies.

The secondary objectives of the study are to evaluate the efficacy of upadacitinib 45 mg QD comparing with placebo in ranked secondary endpoints of achieving endoscopic improvement, endoscopic remission, clinical response per Adapted Mayo Score, clinical response per Partial Adapted Mayo score, histologic-endoscopic mucosal improvement, no bowel urgency, no abdominal pain, histologic improvement, mucosal healing, and change in IBDQ total score and FACIT-F score.

The study will allow enrollment of up to 30% of enrolled bio-IR subjects who have failed 3 or more biologics. Among non-bio-IR subjects, subjects who have used a biologic up to 1 year and have discontinued for reasons other than inadequate response, loss of response, or intolerance (e.g., change of insurance/reimbursement, well-controlled disease, etc.) may be enrolled but must meet other criteria for inadequate response, loss of response, or intolerance to aminosalicylates, corticosteroids, or immunosuppressants as defined in the protocol. The study will allow for enrollment of up to 20% enrolled non-bio-IR subjects who could also have previous use of a biologic therapy but discontinued based on reasons other than inadequate response, loss of response, or intolerance. The study will also evaluate the efficacy of an additional 8-week upadacitinib 45 mg QD treatment in subjects who did not achieve clinical response in the initial 8-week induction phase.

Study Population:

Males and females between 18 and 75 years of age with a diagnosis of moderately to severely active UC. Adolescent males and females 16 and 17 years of age with body weight ≥40 kg and meet the definition of Tanner Stage 5 will be enrolled if approved by the country or regulatory/health authority. If these approvals have not been granted, only subjects ≥18 years old will be enrolled. The study will consist of a mixed population: biologic-inadequate responders (bio-IR) and non-biologic-inadequate responders (non-bio-IR). The number of enrolled non-biologic-inadequate responders (non-bio-IR) subjects will be at least 25% and not exceed 50%.

This study will allow enrollment of up to 30% of enrolled bio-IR subjects who have failed 3 or more biologics. Among non-bio-IR subjects, subjects who have used a biologic up to 1 year and have discontinued for reasons other than inadequate response, loss of response, or intolerance (e.g., change of insurance/reimbursement, well-controlled disease, etc.) may be enrolled but must meet other criteria for inadequate response, loss of response, or intolerance to aminosalicylates, corticosteroids, or immunosuppressants as defined in the protocol. The study will allow for enrollment of up to 20% enrolled non-bio-IR subjects who could also have previous use of biologic therapy but discontinued based on reasons other than inadequate response, loss of response, or intolerance.

The study duration could be up to 25 weeks (excluding a possible washout period), including a Screening Period of up to 5 weeks, an 8-week double-blind Induction Period, an 8-week Open Label Extended Treatment Period (for eligible subjects), and a 30-day Follow-Up Period, if the subject does not meet eligibility to proceed to Study M14-234 Substudy 3.

Number of Subjects to be Enrolled:

A total of approximately 462 subjects will be enrolled worldwide. The number of non-bio-IR subjects enrolled will be at least 25% and not exceed 50% of the total number of subjects enrolled.

Methodology:

At the end of either Week 8 (Part 1) or Week 16 (Part 2), if subjects are eligible, they will be offered an opportunity to participate in Study M14-234 Substudy 3 which is a Phase 3 study designed to evaluate the efficacy and safety of oral administration of upadacitinib 15 mg or 30 mg compared to placebo as maintenance therapy in subjects with moderately to severely active UC who achieved clinical response following induction with upadacitinib in Study M14-675.

Subjects who consent and meet all of the inclusion criteria and none of the exclusion criteria will be enrolled into Study M14-675, which consists of two parts: (Part 1) a randomized, double-blind, placebo-controlled 8-week induction study; and (Part 2) an 8-week Extended Treatment Period for clinical non-responders from Part 1.

Part 1

In Part 1, approximately 462 subjects will be randomized in a 2:1 ratio to double-blind upadacitinib 45 mg QD or matching placebo for 8 weeks. The randomization will be stratified by bio-IR status (bio-IR vs non-bio-IR), corticosteroid use (yes or no) and Adapted Mayo score (≤7 or >7) at Baseline. Within bio-IR, the randomization will be further stratified by number of prior biologic treatments (≤1 or >1). Within non-bio-IR, the randomization will be further stratified by previous biologic use (yes or no).

Treatment groups for Part 1 include:

-   -   Group 1: Upadacitinib 45 mg QD (blinded, n=308)     -   Group 2: Placebo QD (blinded, n=154)

At Week 8, subjects achieving clinical response, defined as a decrease from Baseline in the Adapted Mayo score ≥2 points and ≥30% from Baseline, PLUS a decrease in rectal bleeding subscore (RBS)≥1 or an absolute RBS≤1 may be eligible to enter the 52-week, double-blind, maintenance portion of Study M14-234 (Substudy 3).

All subjects who do not achieve clinical response at Week 8 will be eligible to participate in Part 2 (Extended Treatment Period) to receive open-label upadacitinib 45 mg QD for an additional 8 weeks.

Part 2

Part 2 is an open-label, 8-week Extended Treatment Period for subjects who do not achieve clinical response at Week 8 in Part 1. The objectives of Part 2 are to offer upadacitinib induction treatment to placebo clinical non-responders from Part 1 and to evaluate delayed clinical response of upadacitinib in subjects who do not initially respond during Part 1. The blind from Part 1 will not be broken for the duration of the study as subjects will be assessed as clinical non-responders at the 8 Week Visit of Part 1 and will be moved to Part 2 for further treatment in the study without identifying their initial treatment assignment. All eligible subjects entering Part 2 will receive open-label treatment with upadacitinib 45 mg QD for 8 additional weeks (until Week 16). At Week 16, an endoscopy will be performed to evaluate the treatment effect. A flexible rectosigmoidoscopy is recommended. However, the use of flexible sigmoidoscopy or colonoscopy is at the investigators' discretion based on local practice.

During Part 2, subject with persistent symptoms or worsening UC may be discontinued at any time. At Week 16, subjects who achieve clinical response may be eligible to enter Study M14-234 (Substudy 3) for further blinded treatment. Subjects who do not achieve clinical response at Week 16 will be discontinued from the study and will not be eligible to enroll in Study M14-533 (long term extension)

All subjects will be provided with a Subject Diary (eDiary) at Screening in Study M14-675 where they will record UC-related symptoms, use of anti-diarrheals, and use of medications for endoscopy preparation. For the assessment of the clinical endpoints, the stool frequency and the rectal bleeding subscore will be calculated as an average of the entries recorded into the subject's diary from the most recent consecutive 3-day period prior to each study visit. If diary entries from the 3 consecutive days prior to the visit are not available, the 3 most recent consecutive days in the last 10 days will be utilized. If data is not available for 3 consecutive days, the average of the entries from the most recent 3 non-consecutive days in the last 10 days will be utilized. Clinical endpoints of abdominal pain and bowel urgency from subject diaries will be measured at the same time period as the stool frequency and rectal bleeding subscores. Proportion of subjects who report no abdominal pain and proportion of subjects who report no bowel urgency in the 3 days will be estimated.

At each study visit, a routine physical examination including evaluation of vital signs, evaluation of extra-intestinal manifestations (EIMs), diary review, monitoring for adverse events (AEs), review of concomitant medications, and completion of laboratory assessments will be performed. A full physical examination will be performed at Screening, Baseline, Week 8 and Week 16/Premature Discontinuation (PD) (for subjects who enter the Extended Treatment Period) and must include an evaluation of extra-intestinal manifestations. Symptom based physical examinations will be performed at all other visits at a minimum, but evaluation of EIMs will still be completed at every study visit.

Subjects will undergo a full colonoscopy with biopsy for histologic assessment during Screening with local investigator assessment for Mayo endoscopic subscore for initial eligibility assessment, confirmed by a central reader prior to randomization. At end of treatment (Week 8 in Part 1) a full colonoscopy or flexible sigmoidoscopy, depending on the extent of disease at Screening, will be performed.

For subjects in Part 2, an endoscopy will be performed at Week 16/PD. A flexible rectosigmoidoscopy is recommended at Week 16/PD, however, the use of flexible rectosigmoidoscopy or colonoscopy will be based on the investigator's discretion per local practice.

The endoscopic subscore result from the central reader during the screening period will be used to evaluate the eligibility of a subject to enroll in the study and for all efficacy assessments at Week 8 of Part 1. However, for re randomization into Substudy 3, the endoscopic subscore at Week 8 (Study M14 675 Part 1) or Week 16 (Study M14-675 Part 2) based on the local reader's assessment will be used to determine clinical response status compared to the Baseline assessment of the central reader for enrollment into Study M14-234 Substudy 3.

In addition to the Mayo endoscopic subscore, the central reader will assess the endoscopy findings using the Ulcerative Colitis Endoscopic Index of Severity (UCEIS) scoring system for additional exploratory analyses. Blood samples will be collected for high sensitivity C-reactive protein (hs-CRP), upadacitinib plasma concentrations and other biomarker analyses. In addition, stool samples for fecal calprotectin will be collected. The stool samples should be taken before starting bowel preparations for scheduled endoscopies.

Subjects will be asked to fill out the Inflammatory Bowel Disease Questionnaire (IBDQ), Work Productivity and Activity Impairment (WPAI), European Quality of Life 5 Dimensions 5 Levels (EQ 5D-5L), Short Form 36 Item (SF-36), and Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), Ulcerative Colitis Symptoms Questionnaire (UC-SQ), and Patient Global Impression of Severity (PGIS; only in select sites) during the study at Baseline, Week 2, and Week 8/PD for Part 1. These same questionnaires will be completed at Week 16/PD for Part 2. Subjects will be asked to fill out the Patient Global Impression of Change (PGIC) during the study at Week 2, and Week 8/PD for Part 1. This same questionnaire will be completed at Week 16/PD for Part 2. During each study visit subjects will also be asked to report UC-related hospitalizations and surgeries which will be captured as a part of the supplemental Health Care Resource Utilization (HCRU) form of Adverse Event collection in electronic data capture.

Subjects will be discontinued from the study if they withdraw consent or if they are deemed unsuitable to continue for any reason by the investigator.

Washout Period:

Subjects, who have been taking exclusionary medications prior to screening must complete medication washout. The duration is based on the excluded medication as described in the protocol. However, for subjects who have discontinued infliximab, certolizumab, adalimumab, golimumab, vedolizumab, natalizumab, ustekinumab, if there is proper documentation of an undetectable drug level measured by a commercially available assay for any of the approved biologics above, there is no minimum washout prior to Baseline. Protocol-related adverse events should be reviewed and subjects must complete the washout prior to the Baseline Visit.

Concomitant UC-Related Medications (Oral Corticosteroids, Antibiotics, Aminosalicylates, and/or Methotrexate):

Parts 1 and 2

All UC-related concomitant medications should be kept on stable doses in Parts 1 and 2. All subjects receiving stable dose of UC-related antibiotics (those subjects who did not discontinue), aminosalicylates, or MTX at Week 0 will maintain their concomitant treatments and respective doses through the end of the study. Dose may be decreased or terminated in the event of moderate to severe treatment related toxicity (e.g., leukopenia or elevated liver enzymes) in the opinion of the investigator.

Diagnosis and Main Criteria for Inclusion/Exclusion:

Criteria for Evaluation:         Efficacy:         Primary Endpoint:

The primary endpoint for Study M14-675 is the proportion of subjects who achieve clinical remission per Adapted Mayo score (defined as stool frequency subscore [SFS]≤1 and not greater than baseline, RBS of 0, and endoscopic subscore ≤1) at Week 8. Note: evidence of friability during endoscopy in subjects with otherwise “mild” endoscopy activity will confer an endoscopic subscore of 2.

Ranked Secondary Endpoints:

-   -   1. Proportion of subjects with endoscopic improvement at Week 8     -   2. Proportion of subjects with endoscopic remission at Week 8     -   3. Proportion of subjects achieving clinical response per         Adapted Mayo Score at Week 8     -   4. Proportion of subjects achieving clinical response per         Partial Adapted Mayo score (defined as decrease from Baseline ≥1         points and ≥30% from Baseline, PLUS a decrease in RBS≥1 or an         absolute RBS≤1) at Week 2     -   5. Proportion of subjects achieving histologic-endoscopic         mucosal improvement at Week 8     -   6. Proportion of subjects who reported no bowel urgency at Week         8     -   7. Proportion of subjects who reported no abdominal pain at Week         8     -   8. Proportion of subjects who achieved histologic improvement at         Week 8     -   9. Change from Baseline in IBDQ total score at Week 8     -   10. Proportion of subjects with mucosal healing at Week 8     -   11. Change from Baseline in FACIT-F score at Week 8.         Pharmacokinetic:

Blood samples will be collected for measurement of upadacitinib plasma concentration at Week 2, Week 6, and Week 8/PD in Part 1.

Safety:

Safety analyses will be performed on all subjects who receive at least one dose of study drug. Incidence of AEs, changes in vital signs, electrocardiogram, physical examination results, and clinical laboratory data will be assessed.

Exploratory Research Variables and Validation Studies (Optional):

Prognostic, predictive and pharmacodynamics biomarkers signatures may be investigated. Samples for different applications, including pharmacogenetic, epigenetic, transcriptomic, proteomic and targeted investigations will be collected at various time points. Assessments will include but may not be limited to nucleic acids, proteins, metabolites or lipids.

8-Week Induction Period—Part 1

This period will begin at the Baseline Visit (Week 0) and will end at the Week 8 Visit. At the Baseline Visit, subjects who meet all the inclusion criteria and none of the exclusion criteria described herein will be enrolled into the study and randomized to the double-blind induction period. During this period of the study, subjects will visit the study site at Weeks 2, 4, 6, and 8. A ±3-day window is permitted around scheduled study visits. The last dose of study drug during this period is recommended to be taken the day prior to the Week 8 Visit when possible.

8-Week Extended Treatment Period—Part 2

The period will begin after the Week 8 endoscopy in Part 1 and will end at the Week 16 Visit.

At Week 8, subjects in Part 1 who did not achieve clinical response (defined by Adapted Mayo Score) will be enrolled into Part 2 and receive open label upadacitinib 45 mg QD for an additional 8 weeks. Clinical response is defined as decrease from baseline in the Adapted Mayo score ≥2 points and ≥30% from baseline, PLUS a decrease in rectal bleeding score (RBS)≥1 or an absolute RBS≤1.

If the subject is a clinical responder at Week 8/16, the subject may enter Study M14-533 Cohort 1. If the subject is a clinical non-responder at Week 8, the subject may enter Part 2. If the subject is a clinical non-responder at Week 16 the subject will discontinue from the study. During this period of the study, subjects will visit the study site at Weeks 10, 12, 14, and 16. A ±3-day window is permitted around scheduled study visits. The last dose of study drug during this period is recommended to be taken the day prior to the Week 16 Visit when possible.

Re-Screen

Subjects that initially screen fail for the study will be permitted to re-screen following re-consent. For any subjects who screened and who were unable to enter the program during Study M14-234 Substudy 1 due to enrollment limits, these subjects may also be rescreened into Study M14-234 Substudy 2 or Study M14-675.

The subject must meet all the inclusion and none of the exclusion criteria at the time of re-screening in order to qualify for the study. There is no minimum period of time a subject must wait to re-screen for the study and there is no maximum number of re-screens allowed for a given subject. If the subject had a complete initial screening evaluation including the assessment of a purified protein derivative (PPD) test (or equivalent), or Interferon-Gamma Release Assay (IGRA; QuantiFERON-TB Gold Plus test or T-SPOT TB test), chest x-ray, hepatitis B virus (HBV), hepatitis C virus (HCV), HIV, Beta-D-glucan (Japan only) and electrocardiogram (ECG), these tests will not be required to be repeated for re-screening provided the conditions noted herein are met and no more than 90 calendar days have passed since the date of testing.

If a subject is being rescreened within 14 days (from the date of the previous screening testing), it is not required to repeat Screening testing for chemistry/hematology, urinalysis, serum pregnancy, and Clostridium difficile (C. difficile).

An endoscopy with biopsy will not be required to be repeated for re-screening provided the conditions noted herein are met and re-consent is no more than 30 calendar days after the initial screening endoscopy.

All other screening procedures will be repeated. As appropriate, sites are encouraged to contact the AbbVie TA MD to confirm if subjects should or should not be re-screened. Re-screened subjects will retain the same subject number assigned at the initial screening.

Results of this study are provided in FIGS. 24 to 28C. Generally, upadacitinib 45 mg QD met primary and all ranked secondary endpoints (all achieved p<0.001), demonstrating superiority vs placebo as an induction therapy. This efficacy was demonstrated across clinical, endoscopic and histologic endpoints. At week 8, approximately 75% of patients showed a clinical response (FIGS. 25 and 26B). Of the remaining 25% of non-responding patients, approximately 50% showed a clinical response by 16 weeks. Particularly surprising was the extent of mucosal healing observed after 8 weeks of induction, as defined by an endocopic score of 0 and a Geboes score of less than 2. The proportion of subjects achieving the primary endpoint of clinical remission per Adapted Mayo score at Week 8 was significantly higher in the upadacitinib 45 mg QD group (33.5%) compared to the placebo group (4.1%) with p-value <0.001. Clinical response per Partial Adapted Mayo Score was seen as early as Week 2

Overall, the eight-week treatment with upadicitinib 45 mg QD as an induction therapy was well tolerated. No new safety risks were observed compared to the known safety profile of upadacitinib. The rates of severe adverse events (AE) and AEs leading to study drug discontinuation were lower with upadacitinib 45 mg as compared to placebo. No deaths were reported in the study. The rates of neutropenia, lymphopenia, hepatic disorder, and CPK elevation were higher with upadacitinib 45 mg QD as compared to placebo. The rate of anemia AEs was higher with upadacitinib 45 QD; however, Grade 3 hemoglobin decrease occurred more frequently on placebo. No reports of active TB, malignancy, adjudicated GI perforation, adjudicated VTE, or adjudicated MACE were made in the upadacitinib 45 mg QD group. One event each of adjudicated GI perforation and VTE (PE and DVT) was reported in the placebo group.

Example 20: Upadacitinib 15 mg or 30 mg as Maintenance Therapy for Ulcerative Colitis

Approximately 750 subjects who achieved clinical response per Adapted Mayo Score after completion of induction treatment or Extended Treatment Period in Study M14-234 Substudy 1, Substudy 2, or Study M14-675, were eligible to enter this trial (Substudy 3) and treated with a blinded treatment assignment for up to 52 weeks. Subjects with missing Week 8 or/and Week 16 endoscopy during the period of COVID-19 pandemic were not eligible to enter Substudy 3. Subjects from Study M14-675 were required to have achieved clinical response at Week 8 or 16. The Baseline Visit of Substudy 3 was completed on the same day as the final visit in the Induction Phase (either at Week 8 or Week 16) for subjects who were eligible.

Clinical response was defined as a decrease from baseline in the Adapted Mayo score ≥2 points and ≥30% from baseline, PLUS a decrease in RBS≥1 or an absolute RBS≤1. The treatment assignment in Substudy 3 depended on the treatment received in Substudies 1 and 2, or Study M14-675, as detailed below. Substudy 3 included 4 cohorts:

Cohort 1:

The approximately 525 subjects who achieved clinical response in Study M14-234 Substudies 1 and 2, or Study M14-675, and received 1 of the following treatments, were re-randomized in a 1:1:1 ratio to one of the treatment groups in Cohort 1:

-   -   Upadacitinib 30 mg QD or 45 mg QD in Study M14-234 Substudy 1     -   Upadacitinib 45 mg QD in Study M14-234 Substudy 2 Part 1     -   Upadacitinib 45 mg QD in Study M14-675 Part 1     -   Placebo QD in Study M14-234 Substudy 2 Part 1 followed by         upadacitinib 45 mg QD in Study M14-234 Substudy 2 Part 2     -   Placebo QD in Study M14-675 Part 1 followed by upadacitinib 45         mg QD in Part 2     -   Treatment groups in Cohort 1:         -   Group 1: upadacitinib 15 mg QD         -   Group 2: upadacitinib 30 mg QD         -   Group 3: placebo QD

Subjects who achieved clinical response and received upadacitinib 15 mg QD in Study M14-234 Substudy 1 were re-randomized 1:1 to only receive upadacitinib 15 mg QD or placebo QD (treatment Group 1 or 3).

Cohort 2:

Approximately 60 subjects who received double-blind placebo QD treatment for 8 weeks during Study M14-234 Substudy 1, Substudy 2 Part 1 or Study M14-675 Part 1 and achieved clinical response continued to receive blinded placebo QD in Substudy 3.

Cohort 3:

Approximately 150 subjects who received upadacitinib 45 mg QD in induction phase and did not achieve clinical response—and received upadacitinib 45 mg in Extended Treatment in Study M14-234 (Substudy 2, Part 2) or Study M14-675 (Part 2) and achieved clinical response at Week 16 were re-randomized 1:1 and received blinded upadacitinib 30 mg QD or upadacitinib 15 mg QD in Study M14-234 (Substudy 3).

Cohort 4:

Approximately 15 subjects who received double-blinded treatment of upadacitinib 7.5 mg for 8 weeks during Study M14-234 (Substudy 1) and achieved clinical response continued to receive blinded treatment of upadacitinib 7.5 mg QD in Substudy 3. The schematic of Substudy 3 is provided in Table 30.

M14-234 Substudy 3 (Maintenance study; Cohorts Status week 0-52) Cohort 1: Re-randomized Double blind (DB) Clinical responders to upadacitinib upadacitinib from: 15 mg QD; M14-234 SS1* (not including n = 150 7.5 mg QD) DB upadacitinib SS2 or M14-675 (week 8) 30 mg QD; Extended treatment clinical n = 150 responders (week 16) who DB placebo QD; received placebo in induction n = 150 Cohort 2: Do not get DB placebo QD Placebo clinical responders re-randomized (week 8) from M14-234 SS1, SS2, or M14-675 Cohort 3: Re-randomized DB upadacitinib Clinical responders (week 16) to 15 mg QD upadacitinib from the extended DB upadacitinib treatment period in M14-234 30 mg QD SS2 and M14-675 who received upadacitinib in induction Cohort 4: Do not get DB upadacitinib Clinical responders (week 8) to re-randomized 7.5 mg QD upadacitinib 7.5 mg QD in M14- 234 SS1 *Responders who received upadacitinib 15 mg QD in M14-234 SS1 will only be randomized to receive upadacitinib 15 mg QD or placebo QD

The rationale for re-randomizing only induction responders who received upadacitinib 15, 30 or 45 mg QD from Substudy 1 is to ensure that no subject receives a dose during maintenance that is higher than what was received in the induction period.

During Substudy 3, subjects who met the criteria for initial loss of response after at least 2 weeks of treatment and had a second confirmed loss of response on a consecutive visit at least 14 days later had the option to enroll into Study M14-533 and receive open-label upadacitinib.

Loss of response is defined as follows: A subject who presents with an SFS and RBS score each at least 1 point greater than the end-of-induction value (Week 8 of Substudy 1, Substudy 2 Part 1, Study M14-675 Part 1 or Week 16 of Substudy 2 Part 2 or Study M14-675 Part 2) on two consecutive visits at least 14 days apart, associated with the presence of signs or symptoms of progression of UC.

For subjects with SFS or RBS≥2.1 at the end-of-induction, loss of response is defined as: An increase in either the SFS or RBS of at least 1 point greater than the end-of-induction value on two consecutive visits at least 14 days apart and associated with the presence of signs or symptoms of progression of UC disease.

Subjects who entered Substudy 3 from Study M14-234 Substudy 1 were only required to complete 44 weeks of maintenance therapy in Substudy 3. Subjects entering Substudy 3 from Study M14-234 Substudy 2 or from Study M14-675 were required to complete 52 weeks in Substudy 3 if they did not withdraw or have loss of response prior.

Screening

Subjects, who have been taking exclusionary medications prior to screening or Baseline were required to complete medication washout. The duration was based on the excluded medication. During Screening, biologic drug levels could be optionally assessed as an alternative to completing the required washout period as follows: (1) infliximab and natalizumab: may be tested approximately 4 weeks or later from the last dose; (2) adalimumab, certolizumab, golimumab, or vedolizumab: may be tested approximately 6 weeks or later from the last dose; (3) ustekinumab: may be tested approximately 8 weeks or later from the last dose. If the biologic drug was not detected, the subject was considered as eligible and the washout period was not required.

Concomitant UC-Related Medications (Oral Corticosteroids, Antibiotics, Aminosalicylates, and/or Methotrexate):

At Baseline of Substudy 3 (Week 8 or Week 16 of Study M14-234 Substudy 1, Substudy 2, and Study M14-675), subjects who were taking corticosteroid therapy will have their corticosteroid therapy tapered. Subjects taking corticosteroids who have worsening of disease after the steroid taper has been initiated may have had their corticosteroid dose increased. Use of inhaled or topical dermatologic corticosteroids was not restricted.

All subjects receiving UC-related antibiotics may discontinue treatment starting at Week 0 of Substudy 3 at the discretion of the investigator.

All subjects receiving stable dose of UC-related antibiotics (those subjects who did not discontinue), aminosalicylates, or MTX at Week 0 maintained their concomitant treatments and respective doses through the end of the study. Dose was allowed to be decreased or terminated in the event of moderate to severe treatment related toxicity (e.g., leukopenia or elevated liver enzymes. If the subject and investigator chose to receive/administer live vaccines, these vaccinations were completed (per local label) at least 30 days (8 weeks for subjects in Japan) before first dose of study drug. Live vaccinations were prohibited during study participation including at least 30 days (or longer if required locally) after the last dose of study drug.

Efficacy Assessment

The primary endpoint for Phase 3 maintenance (Substudy 3) is the proportion of subjects who achieve clinical remission per Adapted Mayo score at Week 52 (for subjects who enrolled under the protocol with 44-week maintenance period, these will apply at Week 44, as applicable).

Ranked secondary efficacy variables for Phase 3 Maintenance (Substudy 3) are as follows:

The following outcomes and questionnaires will be completed:

-   -   IBDQ—Inflammatory Bowel Disease Questionnaire. The IBDQ is a         disease-specific instrument composed of 32 Likert-scaled items.         The total score ranges from 32 to 224 using the 7-point response         options, with higher scores indicating better health-related         quality of life. The IBDQ scale contains 4 component subscales:         bowel symptoms, systemic symptoms, emotional function, and         social function. Each subscale can be computed with total scores         ranging from 10 to 70, 5 to 35, 12 to 84, and 5 to 35,         respectively. In some embodiment, patients treated according to         the disclosed method exhibit a change (increase from baseline)         in the IBDQ score.     -   SF-36—Short Form 36. The SF-36 questionnaire is a         self-administered multi-domain scale with 36 items. Eight         subscales cover a range of functioning: physical functioning,         role-physical, bodily pain, general health, vitality, social         functioning, role-emotional, and mental health. The scoring         yields a physical component score, a mental component summary         score, and subscale scores. Higher scores represent better         outcomes. The concepts measured by the SF-36 are not specific to         any age, disease, or treatment group, allowing comparison of         relative burden of different diseases and the benefit of         different treatments.     -   EQ-5D-5L—European Quality of Life 5 Dimensions 5 Levels. The         EQ-5D-5L is a standardized non-disease specific instrument for         describing and valuing health-related quality of life. The         EQ-5D-5L consists of 5 dimensions: mobility, self-care, usual         activity, pain/discomfort, and anxiety/depression. Each         dimension has 5 levels: no problem, slight problem, moderate         problem, severe problem or unable to do the activity. It also         contains a Visual Analogue Scale (VAS). Subjects are asked to         indicate the level that describes their current level of         function or experience for each dimension. As a measure of         health status, it provides a descriptive profile and can be used         to generate a single index value for health status, where full         health is equal to 1 and death is equal to 0. The VAS records         the subject's assessment of his/her own health along a vertical         20 cm line, which has health state scores between 0 and 100.     -   FACIT-F—Functional Assessment of Chronic Illness         Therapy-Fatigue. The FACIT system is a collection of quality of         life (QOL) questionnaires targeted to the management of cancer         and other chronic illnesses. The FACIT fatigue (FACIT-F)         questionnaire was developed to assess fatigue associated with         anemia. It consists of 13 fatigue-related questions. The         responses to the 13 items on the FACIT fatigue questionnaire are         each measured on a 4-point Likert scale. The responses to the         answers are the following: (i) not at all: 0 points; (ii) a         little bit: 1 point; (iii) somewhat: 2 points; (iv) quite a bit:         3 points; (v) very much: 4 points. Thus, the total score ranges         from 0 to 52. High scores represent less fatigue. In some         embodiment, patients treated according to the disclosed method         exhibit a change (reduction from baseline) in the FACIT-F score.     -   WPAI—Work Productivity and Activity Impairment Questionnaire         Ulcerative Colitis. The Work Productivity and Activity Index         assesses the impact of the condition on work productivity losses         and impairment in daily activity. WPAI has six items covering         four domains: (1) Absenteeism (work time missed), measured as         the number of hours missed from work in the past 7 days due to a         condition related problems. Scores are expressed as impairment         percentages, adjusting for hours actually worked according to         the WPAI scoring algorithm; (2) Presenteeism (impairment at         work/reduced on-the-job effectiveness), measured as the impact         of the condition on productivity while at work (i.e., reduced         amount or kind of work, or not as focused as usual). Responses         are recorded on a 0-10 Likert scale (where, 0=no effect of UC on         work and 10=severe impact of UC while at work); (3) Productivity         loss (overall work impairment), measured as the sum of hours         missed due to condition (i.e., absenteeism) and number of hours         worked with impairment (i.e., product of number of hours worked         and presenteeism); and (4) Activity impairment (i.e., activities         other than paid work like work around house, cleaning, shopping,         traveling, studying), recorded and scored in the same way as         presenteeism. Higher numbers indicate greater impairment and         less productivity.     -   PGIC—Patient Global Impression of Change. The PGIC is a         self-administered instrument that assesses change in the overall         symptoms due to UC. The PGIC is one item in which subjects are         asked to rate overall improvement since start of the treatment.         Subjects rate their change as “Very much improved,” “Much         improved,” “Minimally improved,” “No change,” “Minimally worse,”         “Much worse” and Very much worse.     -   PGIS—Patient Global Impression of Severity. The PGIS is a         self-administered instrument that assesses the severity of the         overall symptoms due to ulcerative colitis. The PGIS is one item         in which subjects are asked to rate overall severity of symptoms         over the past week. Subjects rate their change as “Absent,”         “Minimal,” “Mild,” “Moderate,” “Moderately severe,” “Severe” and         “Very severe.”     -   UC-SQ—Ulcerative Colitis Symptoms Questionnaire. The Ulcerative         Colitis Symptoms Questionnaire (UC-SQ) is a UC-specific         instrument composed of 17 items. UC-SQ was developed to assess         UC related gastrointestinal symptoms (e.g., frequent bowel         movements, abdominal pain, cramping) and nongastrointestinal         symptoms (e.g., joint pain and sleep difficulties). Each symptom         item 1-9 can be responded on Likert-type of options such as (i)         Not at all: 0 points; (ii) A little bit: 1 point; (iii)         Somewhat: 2 points; (iv) Quite a bit: 3 points; (v) Very much: 4         points. Each symptom item 10-17 can be responded on Likert-type         of options such as (i) Never: 0 points; (ii) Rarely: 1         point; (iii) Sometimes: 2 points; (iv) Often: 3 points; (v)         Always: 4 points. Overall symptom scores are calculated by         combining ratings of the individual items, with higher scores         indicating greater severity.     -   HCRU—Health Care Resource Utilization. Health Care Resource         Utilization data on number of all-cause and UC-related         hospitalizations and surgeries will be collected         Results

Results of this study are provided in FIGS. 29 to 41E. Overall, the study met the primary and all ranked secondary endpoints, demonstrating superiority of upadacitinib at doses of 15 mg and 30 mg once daily, as maintenance therapy for 52 weeks versus placebo (PBO, withdrawal from upadacitinib treatment; p<0.001) in subjects with moderately to severely active Ulcerative Colitis (UC) who responded to 8 weeks of upadacitinib 45 mg once daily induction treatment (FIG. 29 ). The primary endpoint of clinical remission per Adapted Mayo score at Week 52 was achieved by statistically significantly higher proportion of subjects in both upadacitinib treatment groups (42.3% for upadacitinib 15 mg, and 51.7% for upadacitinib 30 mg) than in the PBO group (withdrawal from upadacitinib treatment: 12.1%; p<0.001). Corticosteroid-free remission was achieved in 57% of patients in the 15 mg cohort and 68% of patients in the 30 mg cohort, and who were in remission at the completion of the 8-week induction studies. These rates were significantly higher for the 15 mg and 30 mg upadacitinib treated patients relative to the placebo group (22%; (p<0.001). The maintenance efficacy results are summarized in Table 32. An overview of primary and ranked secondary endpoints is provided in FIG. 29 .

N = 47, 58 and 54 for upadacitinib 15 mg, upadacitinib 30 mg, and placebo group, respectively.

As shown in FIG. 30 and FIG. 31 , the clinical response per Partial Adapted Mayo Score and clinical remission rate per Partial Mayo Score was maintained over time until Week 52 in both upadacitinib groups. Clear dose response was observed in the primary and most of the secondary endpoints. The remission rates at 30 mg were generally higher than at 15 mg across the primary and secondary endpoints, Endoscopic remission and mucosal healing remission rate were similar in the 15 mg and 30 mg groups.

Upadacitinib pharmacokinetics were consistent between the induction and maintenance periods in subjects with UC. Both upadacitinib doses were generally safe and well tolerated in subjects with UC. No new safety risks were identified in this UC study compared to the known safety profile of upadacitinib.

Statistical Analysis

The primary efficacy objective was assessed on the ITTA population, which was planned to comprise of the first 450 subjects enrolled under 52-week maintenance protocol in Cohort 1; subjects received 8-week UPA 45 mg QD induction treatment and at least 1 dose of study drug in the Maintenance Study. The 450 subjects were planned to be randomized in a 1:1:1 ratio to upadacitinib 15 mg QD, upadacitinib 30 mg QD or placebo. The randomization was stratified by Bio-IR status (Bio-IR; non-Bio-IR) at the Induction Baseline (referred to as Baseline hereafter), clinical remission status at Week 0 of the Maintenance Study (referred to as Week 0 hereafter) (yes; no), corticosteroid usage at Week 0 (yes; no), and induction dosage for subjects enrolled from the Phase 2b Induction Study.

The ITTA population included 451 subjects. Key demographics and baseline characteristics were generally balanced across treatment groups. A higher rate of discontinuation from study drug was observed in placebo group (65.8%) vs. upadacitinib treatment groups (upadacitinib 15 mg QD group 33.1%, and upadacitinib 30 mg 21.4%), primarily due to lack of efficacy (Table 33).

Response rate in clinical remission per Adapted Mayo Score at Week 52 was consistent across subgroups of Bio-IR and Non-Bio-IR (Table 34 and Forest plots (FIG. 32 and FIG. 33 )). The 95% confidence intervals for the treatment difference between each UPA dose and placebo in all subgroups excluded zero favoring upadacitinib, except those with sample size <5.

Further graphical illustrations of study results with respect to various endpoints, as well as exposure-response relationships, are provided in FIGS. 34-41E. Notably, a trend was observed for increase in the % of subjects achieving each of the evaluated endpoints with increasing upadacitinib C_(avg) (FIGS. 40A-40E), Specifically, an exposure-response trend was observed for Week 52 clinical remission, clinical remission & steroid free for ≥90 days (among all subjects in maintenance), endosopic improvement, endoscopic remission, and HEMI within the 15 mg to 30 mg exposure range. The trend was less apparent for endoscopic remission than for the other efficacy endpoints. The efficacy exposure-response trends were more clearly observed in subjects who had not achieved clinical remission at the end of induction than in those had achieved remission at the end of induction. Based on preliminary exposure-response models, 30 mg is predicted to provide ˜8% to 10% greater efficacy for clincial remission, clinical remission & steroid free for ≥90 days, endosopic improvement, and HEMI compared to 15 mg QD exposures. Without wishing to be bound by theory, the data suggests that exposures from the 15 mg dose may be adequate in patients who achieved remission at at end of 8-weeks of induction.

Example 21: Clinical Study for Crohn's Disease

This study (Study M14-431) was a Phase 3, randomized, double-blind, placebo-controlled induction study to evaluate the safety and efficacy of upadacitinib (UPA) compared to placebo (PBO) in adult subjects with moderately to severely active Crohn's disease (CD) who have inadequately responded to or are intolerant to biologic therapy (Bio-IR). This study was part of an overall induction and maintenance study program as illustrated in FIG. 42 and FIG. 43 .

Study Population:

Males and females between 18 and 75 years of age (or minimum age of adult consent according to local regulations) with a confirmed diagnosis of CD for at least 3 months and moderately to severely active CD who have inadequately responded to or are intolerant to biologic therapy. Moderately to severely active CD was defined by: Average daily very soft or liquid stool frequency (SF)≥4 AND/OR average daily abdominal pain (AP) score ≥2 (values represent the unweighted daily averages of the corresponding subscores from the Crohn's Disease Activity Index [CDAI]); and Evidence of mucosal inflammation, defined as Simplified Endoscopic Score for CD (SES-CD)≥6 (≥4 for subjects with isolated ileal disease), excluding the presence of narrowing component. Subjects must have had an inadequate response or intolerance to one or more biologic agents for CD (adalimumab, certolizumab, infliximab, ustekinumab and/or vedolizumab). The study allowed enrollment of up to 35% of subjects who have demonstrated inadequate response or intolerance to 3 or more biologics.

Methodology:

Study M14-431 was a Phase 3, randomized, double-blind, placebo-controlled induction study to evaluate the efficacy and safety of upadacitinib, an orally administered Janus kinase 1 inhibitor, in adult subjects with moderately to severely active CD who have inadequately responded to or are intolerant to biologic therapy. Subjects who consent and meet all of the inclusion criteria and none of the exclusion criteria were enrolled into this study, which encompassed 3 parts: (Part 1) a randomized, double-blind, placebo controlled induction; (Part 2) an open-label, single-arm active induction; and (Part 3) an Extended Treatment Period for non-responders from Part 1 or Part 2.

Part 1

In Part 1, subjects (n=495) were randomized in a 2:1 ratio to upadacitinib 45 mg once daily (QD) or matching placebo for 12 weeks. The randomization was stratified by baseline corticosteroid use (yes or no), endoscopic disease severity (SES-CD<15 and ≥15), and number of prior biologic treatments (>1 and ≤1). The data collected from subjects from Part 1 was used for the primary efficacy analysis. Visits during the study were to occur at Baseline and Weeks 2, 4, 8, and 12/Premature Discontinuation (PD) to collect clinical, endoscopic, and laboratory assessments of disease activity. The last dose of study drug during this period was to be taken the day prior to the Week 12 visit.

At Week 12, subjects achieving clinical response, defined as ≥30% decrease in average daily very soft or liquid SF and/or ≥30% decrease in average daily AP score (both not worse than Baseline) were eligible to enter the 52-week, double-blind, maintenance portion of Study M14-430. All subjects who did not achieve clinical response at Week 12 were enrolled in Part 3 (Extended Treatment Period) and receive double-blind upadacitinib until Week 24/PD. Subjects were not eligible to enter Study M14-430 until the ileocolonoscopy procedure at Week 12 was completed. If the COVID-19 pandemic precluded a subject from undergoing an endoscopy, the subject was enrolled in Study M14-430 if clinical response was achieved at Week 12.

Part 2

Part 2 was an open-label portion (open-label cohort) of this study. Once enrollment in Part 1 was complete, 129 subjects were enrolled in Part 2 to receive open-label upadacitinib 45 mg QD for 12 weeks. The objective of Part 2 was to have a sufficient number of subjects with clinical response re-randomized in the double-blind, maintenance portion of Study M14-430, while minimizing unnecessary exposure to placebo. The data collected from subjects from Part 2 were not part of the primary efficacy analysis for this study, used descriptive statistics, and were reported separately in the clinical study report. Visits during the study occurred at Baseline and Weeks 2, 4, 8, and 12/PD to collect clinical, endoscopic, and laboratory assessments of disease activity. At Week 12, subjects achieving clinical response were eligible to enter Study M14-430. Subjects who did not achieve clinical response at Week 12 were eligible to participate in Part 3 (Extended Treatment Period) to receive open-label upadacitinib 30 mg QD until Week 24/PD.

Part 3

Part 3 was a 12-week Extended Treatment Period consisting of 3 cohorts of subjects who did not achieve clinical response at Week 12 in Part 1 or Part 2. Clinical response was defined as ≥30% decrease in average daily very soft or liquid SF and/or ≥30% decrease in average daily AP and both not greater than Baseline. The objectives of Part 3 were to offer blinded upadacitinib induction treatment to placebo non-responders from Part 1 and to evaluate delayed clinical response to upadacitinib in subjects who did not initially respond to upadacitinib during Part 1 or Part 2. Part 3 consisted of 3 cohorts, and the treatment assignment depended on the treatment received in Part 1 or Part 2, as follows:

-   -   Cohort 1: Subjects who received placebo in Part 1 and did not         achieve clinical response at Week 12 are eligible to receive         double-blind induction treatment with upadacitinib 45 mg QD for         12 weeks (until Week 24).     -   Cohort 2: Subjects who received double-blind upadacitinib in         Part 1 and did not achieve clinical response at Week 12 were         eligible to receive double-blind upadacitinib 30 mg QD for 12         weeks (until Week 24).     -   Cohort 3: Subjects who received open-label upadacitinib during         Part 2 and did not achieve clinical response at Week 12 were         eligible to receive open-label upadacitinib 30 mg QD for 12         weeks (until Week 24).

Subjects in Cohort 1 and 2 remained blinded to treatment to avoid unmasking the treatment received during Part 1. The data collected from subjects from Part 3 was not be part of the primary efficacy analysis for this study, used descriptive statistics, and were reported separately in the clinical study report. Subjects were not eligible to enter in Part 3 until the Week 12 endoscopy was completed. If the COVID-19 pandemic precluded a subject from undergoing an endoscopy, and the subject had not achieved clinical response, the subject entered Part 3 of Study M14-431. Visits occurred at Weeks 16, 20 and 24/PD to collect clinical, endoscopic, and laboratory assessments of disease activity. During Part 3, subjects with persistent symptoms or worsening of CD were discontinued.

At Week 24, subjects who achieved clinical response were eligible to enter Study M14-430. Subjects were not eligible to enter Study M14-430 until the ileocolonoscopy procedure at Week 24 for evaluation of mucosal inflammation was completed. If the COVID-19 pandemic precluded a subject from undergoing an endoscopy, the subject was enrolled in Study M14-430 if clinical response was achieved at Week 24. Subjects who do not achieve clinical response at Week 24 were discontinued from Study M14-431 and received standard of care treatment at the investigator's discretion. Subjects who do not achieve clinical response at Week 24 and all subjects who prematurely discontinued the study had a follow-up visit 30 days from the last dose of study drug to collect information on new or ongoing adverse events (AEs) and laboratory assessments. Subjects were discontinued from the study if they withdrew consent or if they were deemed unsuitable to continue for any reason by the investigator. The duration of the study was up to 33 weeks, including Screening Period (5 weeks), a 12-week double-blind or open-label cohort Induction Period (Part 1 and Part 2), a 12-week Extended Treatment Period (Part 3), and a 30-day follow-up for subjects who do not enroll into Study M14-430.

At the Screening Visit, all subjects were provided with an electronic diary. Subjects were instructed and trained on how to record CD-related symptoms (including total and very soft and liquid number of stools and abdominal pain), general well-being and use of antidiarrheals on a daily basis; and use of medications for endoscopy preparation throughout the study. The very soft and liquid stools were defined as consistency Type 6 or Type 7 based on the Bristol Stool Chart. The diary was reviewed by site personnel with the subject at each visit and for the assessment of the clinical endpoints. At each Study Visit, routine physical examination included evaluation of vital signs, extra intestinal manifestations, and presence or absence of fistulas; calculation of CDAI score, average daily very soft or liquid SF and average daily AP (SF and AP entries from the most recent 7-day period prior to each study visit were used); monitoring of AEs; reporting of concomitant medications and laboratory assessments was performed. The very soft or liquid SF and AP score values represented the unweighted daily averages of the corresponding subscores from the CDAI. Additionally, subjects completed quality of life (QoL), CD symptoms, symptoms impact on QoL, and work productivity questionnaires throughout the study. Subjects underwent a full colonoscopy (ileocolonoscopy) for evaluation of mucosal inflammation using the SES-CD. All endoscopies were centrally read to document eligibility at Screening and for Week 12 and 24/PD assessments. Intestinal biopsies during the endoscopic evaluation were collected for histologic assessment and exploratory research during endoscopy visits at Screening, Week 12, and Week 24/PD in approximately 200 subjects (intestinal biopsy substudy). Optional blood samples were collected for exploratory research at Baseline, Week 4, Week 12, and Week 24/PD. Optional stool collections were done at Baseline, Week 4 and Week 12 for exploratory evaluation of biomarkers in approximately 200 subjects (fecal biomarker substudy).

All subjects receiving a stable dose of CD-related antibiotics, aminosalicylates, or methotrexate (MTX) at Baseline maintained their concomitant treatments without dose changes through the end of the study. Initiating and/or changing doses of these medications was prohibited during the study. Doses of CD-related antibiotics, aminosalicylates, or MTX were decreased only in the event of moderate-to-severe treatment related toxicities. Setons were authorized as concomitant therapy in subjects with perianal fistulas and documented in the eCRF under concomitant medications.

Concomitant Corticosteroids

Subjects who entered the study on oral corticosteroids were not allowed to change the corticosteroid dose during the first 4 weeks of the induction treatment period. Doses of corticosteroids were decreased during the first 4 weeks only in the event of moderate-to-severe treatment related toxicities. At Week 4, subjects had their corticosteroid dose reduced according to a tapering schedule as described. At Week 4, subjects who were on prednisone (or oral equivalent) or oral budesonide had their corticosteroid dose tapered, according to the tapering schedule. Subjects who did not achieve clinical response at Week 12 in Part 1 or Part 2, and enter Part 3 without having completed the steroid taper resumed the corticosteroid taper at Week 16, according to the tapering schedule. Initiating locally acting (rectal or suppository) or systemic corticosteroids for any reason was prohibited during the induction treatment period and was considered a protocol deviation and was discussed with the TA MD. Use of inhaled or topical (except rectal or suppository) corticosteroids was not restricted. Subjects were not allowed to be on both budesonide (for CD disease) and prednisone (or equivalent) simultaneously.

Achievement of resolution of extra-intestinal manifestations (EIMs) at Week 12, among subjects with EIMs at Baseline Pharmacokinetic Variables

Upadacitinib plasma concentrations were determined from samples collected at each visit beginning at Week 2. Blood samples at the Week 4 visit were collected prior to dosing if possible. For all other visits, blood samples were collected at any time during the visit. A non-linear mixed effects modeling approach were used to estimate the population central values and the empirical Bayesian estimates of the individual values of upadacitinib oral clearance (CL/F) and volume of distribution (V/F). Additional parameters where estimated when useful in the interpretation of the data.

Safety Variables

Safety analyses were performed on the safety set, which included all subjects who receive at least one dose of study drug. The incidence of AEs, changes in vital signs, physical examination results, and clinical laboratory data were assessed throughout the study. Electrocardiograms were performed at screening, and at the end of each Part 1, 2, 3 of the study. AEs and laboratory data, when available, were graded as described in the National Cancer Institute Common Terminology Criteria for Adverse Events and summarized accordingly. An external, independent Data Monitoring Committee were responsible for monitoring unblended safety data and alerting AbbVie to possible safety concerns related to the conduct of the study.

Statistical Methods

Efficacy

The co-primary endpoints were the proportion of subjects with clinical remission per PROs (EU/EMA) or clinical remission per CDAI (US/FDA) at Week 12 and the proportion of subjects with endoscopic response at Week 12. This study evaluated one induction dose of upadacitinib 45 mg QD. Efficacy analysis was based on all intent-to-treat (ITT) subjects. The ITT analysis set included all randomized subjects who had taken at least one dose of study drug in the double-blind induction period from Part 1. The comparison between treatment groups on the co-primary efficacy endpoints was performed using the Cochran-Mantel-Haenszel (CMH) test and stratified by Baseline corticosteroid use (yes or no), endoscopic disease severity (SES-CD<15 and ≥15), and number of prior biologics used (>1 and ≤1). Both of the co-primary efficacy endpoints were tested at two-sided significance level of 0.05. A CMH-based, two-sided 95% confidence interval for the difference between treatment groups was calculated. If the average daily SF or average daily AP score (EU/EMA) or CDAI (US/FDA) data at Week 12 were missing, the non-responder imputation approach was applied for the clinical remission per PROs and clinical remission per CDAI endpoints, respectively. Subjects who discontinued prior to Week 12 for any reason were considered as “not-achieved” for clinical remission or endoscopic response endpoints. A multiple testing procedure was used to provide strong control of the type 1 error rate at alpha=0.05 (2-sided) across analyses with respect to the co-primary endpoints, and ranked secondary endpoints. Specifically, testing utilized a sequence of hypothesis testing for the co-primary endpoints followed by the ranked secondary endpoints, and began with testing co-primary endpoints using a of 0.05 (2-sided). If both co-primary endpoints achieved statistical significance, continued testing followed a pre-specified weight of α-allocation between individual hypotheses as well as between families of hypotheses. The details of the testing procedure are specified and documented in the statistical analysis plan (SAP). In general, continuous secondary efficacy variables with repeated measurements were analyzed using a Mixed Effect Repeated Measure (MMRM) model. Continuous secondary efficacy variables which were collected at only one post-baseline visit (such as SES-CD) were analyzed using an Analysis of Covariance (ANCOVA) model. Categorical secondary efficacy variables were analyzed using the CMH test controlling for stratification variables. NRI for missing data were used for categorical secondary endpoints.

Pharmacokinetics

A non-linear mixed-effects modeling approach were used to estimate the population central values and the empirical Bayesian estimates of the individual values for upadacitinib oral clearance and volume of distribution. Additional parameters were estimated when useful in the interpretation of the data.

Safety

AEs, laboratory data, and vital signs were the primary safety parameters in this study. All safety comparisons were performed between treatment groups using the safety set. Treatment-emergent AEs were defined as events that began or worsened either on or after the first dose of the study drug and within 30 days after the last dose of the study drug for subjects who did not participate in Study M14-430, or within 30 days after the last dose of study drug in Study M14-431 or first dose of study drug in Study M14-430 if the subject enrolled in Study M14-430, whichever came first. An overview of treatment-emergent AEs, including AEs of special interest, AEs leading to death, AEs leading to PD, AEs by Medical Dictionary for Drug Regulatory Activities preferred term and system organ class, AEs by maximum relationship to study drug, and AEs by maximum severity was summarized by number and percentage. Changes in laboratory data were described using statistical characteristics and comparison between treatment groups performed using a one-way Analysis of Variance. In addition, shift tables and listings were provided for abnormal values, whereby the normal range of the analyzing laboratory was used. Vital signs were analyzed similarly.

Primary Approach to Handle Missing Data

For categorical variables, the primary approach to handle missing data was Non-Responder Imputation (NRI) incorporating Multiple Imputation (MI) for missing data due to COVID-19 (NRI-C). For continuous variables, missing data were handled by Mixed-effect Model Repeat Measurement (MMRM).

Results

Study Summary

This study comprised a 12-week Induction Period (FIG. 45 ), an option of a 12-week Extended Treatment Period (FIG. 46 ), and a 30-day Follow-up Period for subjects who did not roll over to the Maintenance Study M14-430. Subjects which entered the study with background corticosteroid had their corticosteroid dose reduced according to the protocol-specified tapering schedule. The clinical response in FIG. 45 and FIG. 46 was defined as ≥30% decrease in average daily very soft or liquid SF and/or ≥30% decrease in average daily AP score, with both SF and AP not worse than Baseline. With reference to FIGS. 45 and 46 , the Induction and Extended Treatment Periods were designed as follows:

Induction Period (Baseline to Week 12, (FIG. 27 )):

At Baseline, eligible subjects were enrolled to a 12-week Induction Period (double-blinded, placebo (PBO)-controlled [Part 1] or single-arm, open-label [Part 2]). Part 1 was a randomized, double-blind, PBO-controlled part with 12-week induction treatment. Subjects in Part 1 were randomized to either UPA 45 mg QD or matching PBO in a 2:1 ratio. The randomization was stratified by corticosteroid use (yes or no), endoscopic disease severity as evaluated by the Simplified Endoscopic Score for Crohn's Disease (SES-CD; <15 or ≥15), and the number of prior biologic treatments (>1 or ≤1). All primary and secondary efficacy endpoints were analyzed in the ITT1 Population, which was defined as all randomized subjects with at least one dose of study drug in Part 1. To ensure sufficient sample size in the downstream Maintenance Study M14-430, additional subjects were enrolled to a single-arm, open-label arm to receive UPA 45 mg QD 12-week induction treatment (Part 2).

Extended Treatment Period (Week 12 to Week 24, (FIG. 28 ):

At Week 12, subjects who achieved the clinical response were rolled over to the Maintenance Study M14-430, whereas subjects who did not achieve the clinical response entered an Extended Treatment Period (Part 3). Specifically, subjects who received PBO in Part 1 received UPA 45 mg QD (Cohort 1), whereas subjects who received UPA 45 mg QD in Part 1 received UPA 30 mg QD (Cohort 2). Treatments in Cohort 1 and 2 were given in a blinded fashion. Subjects who received UPA 45 mg QD in Part 2 received open-label UPA 30 mg QD (Cohort 3).

Demographic, Baseline Characteristics, and Subject Disposition

A total of 495 subjects were randomized (171 in PBO and 324 in UPA 45 mg) in Part 1, and all were treated. There were 440 (88.9%) subjects who completed the 12-week induction period of study drug in Part 1 (Table 37). Demographics and baseline characteristics were generally balanced between treatment groups (Table 38). Subject disposition in Part 2 and 3 are presented in Table 39.

In patients with moderately to severely active Crohn's disease who had failed one or more biologics, the study demonstrated the superiority of UPA 45 mg QD vs. placebo as induction treatment for 12 weeks in co-primary endpoints (clinical remission per CDAI, clinical remission per PRO and endoscopic response) for both EU/EMA and US/FDA regulatory purposes with p<0.0001 (FIG. 47 ). In addition, 8 out of 10 key secondary endpoints also achieved statistical significance. Efficacy was demonstrated across clinical, endoscopic, steroid-free, fatigue, and quality of life measures. Rapid onset of action was observed (achievement of clinical response and/or remission). Specifically, clinical remission per CDAI and PRO measures was observed as early as week 2 (FIG. 48 and FIG. 49 , respectively). Endoscopic response and endoscopic remission were achieved at week 12 (FIG. 50 ). Steroid-free clinical remission with both CDAI and PRO measures was achieved at the end of induction treatment (week 12) with upadacitinib (FIG. 51 ). Efficacy results and associated statistical measures for primary and key secondary endpoints are shown in Table 40 (EU/EMA) and Table 41 (US/FDA). Consistent efficacy results of co-primary endpoints were observed in the sensitivity analyses, as shown in Table 42. Selected efficacy endpoints at the end of each study part are summarized in Table 43.

Example 22: Upadacitinib 15 mg or 30 mg as Maintenance Therapy for Crohn's Disease

This study (Study M14-430) was a Phase 3, multicenter, randomized, double-blind, placebo-controlled maintenance and long-term extension study of the efficacy and safety of upadacitinib (ABT-494) in subjects with moderately to severely active Crohn's Disease who completed the studies M14-431 or M14-433.

Methodology:

Study M14-430 was a Phase 3, multicenter study to evaluate the efficacy and safety of maintenance and long-term treatment administration of upadacitinib, an orally administered Janus kinase 1 inhibitor, in adult subjects with CD. Subjects who consented and met all of the inclusion criteria and none of the exclusion criteria in each substudy were enrolled. Baseline was defined as the Baseline Visit of Study M14-431 or Study M14-433 (parent study) and Week 0 was defined as the first study visit in Substudy 1 or Substudy 2.

Objectives:

Study M14-430 comprised two substudies.

-   -   Substudy 1 (randomized, double-blind, placebo-controlled         maintenance): To evaluate the efficacy and safety of two doses         of upadacitinib versus placebo as maintenance therapy in         subjects with moderately to severely active Crohn's disease (CD)         who responded to upadacitinib induction treatment in Studies M14         431 or M14-433. Sub-study 1 included a 52-week Maintenance         Period.     -   A schematic of the study design for Substudy 1 is shown in FIG.         52 .

Substudy 2 (long term extension [LTE]): To evaluate safety and efficacy of long-term administration of upadacitinib in subjects with moderately to severely active CD who participated in the Phase 3 upadacitinib induction and maintenance studies. Sub-study 2 included a 240-week LTE Period. A schematic of the study design for Substudy 2 is shown in FIG. 53 .

Study Population:

Substudy 1 enrolled subjects who had achieved clinical response (defined as ≥30% decrease in average daily very soft/liquid stool frequency [SF] and/or ≥30% decrease in average daily abdominal pain [AP] score and both not worse than Baseline) at Week 12 of the induction Study M14-431 or Study M14 433 or after the blinded Extended Treatment Period of Study M14-431 or Study M14-433 at Week 24.

Substudy 2 enrolled subjects who completed Substudy 1 and subjects from Study M14-431 (Part 3/Cohort 3) who received open-label upadacitinib 30 mg once daily (QD) in the Extended Treatment Period and achieved clinical response at Week 24.

Number of Subjects Enrolled: Approximately 747 subjects, with the following allocation:

-   -   Substudy 1: Approximately 717 subjects from Studies M14-431 and         M14-433     -   Substudy 2: Approximately 30 subjects from Study M14-431 and         approximately 573 subjects (80% of subjects in Substudy 1) who         completed Week 52 of Substudy 1.         Substudy 1 (52-Week, Randomized, Double-Blind, Maintenance)

All subjects who achieved clinical response after 12 weeks of induction treatment with upadacitinib or placebo or after blinded treatment in the Extended Treatment Period at Week 24 in Studies M14-431 or M14-433 were eligible to enroll in Substudy 1, and were blinded to treatment assignment. Substudy 1 had three cohorts:

Cohort 1:

Approximately 427 subjects who received upadacitinib 45 mg QD induction treatment for 12 weeks in Study M14-431 (from Part 1 or Part 2) or Study M14-433 (Part 1), and approximately 110 subjects who received upadacitinib 45 mg QD induction treatment for 12 weeks during the Extended Treatment Period of Study M14-431 (Cohort 1 of Part 3) or Study M14-433 (Cohort 1 of Part 2) and achieve clinical response were re-randomized in a 1:1:1 ratio to one of the following three treatment groups:

-   -   Group 1: upadacitinib 15 mg QD     -   Group 2: upadacitinib 30 mg QD     -   Group 3: placebo

The randomization was stratified by prior induction population (1) Study M14-433 non-bio-IR, 2) Study M14-433 bio IR or Study M14-431 Part 1/Part 3, or 3) Study M14-431 Part 2), clinical remission (per PROs) status (yes or no), and endoscopic response status (yes or no; based on the local read) at Week 12 or 24 of Study M14-431 or Study M14-433. The data collected from approximately 501 subjects re-randomized into this cohort was used for the primary efficacy analysis.

Cohort 2:

Approximately 120 subjects who received double-blind placebo for 12 weeks during Part 1 of Studies M14-431 or M14-433 and achieved clinical response were assigned by interactive response technology (IRT) to continue to receive blinded placebo.

Cohort 3:

Approximately 60 subjects who entered the Extended Treatment Period of Studies M14-431 or M14-433 to receive double blind upadacitinib 30 mg QD for 12 weeks and achieved clinical response at Week 24 were assigned by IRT to continue to receive blinded upadacitinib 30 mg QD. The final visit of Study M14-431 or Study M14-433 (Week 12 or Week 24) was the enrollment visit into Substudy 1. The day of enrollment of Study M14-430 was considered the Week 0 visit of Substudy 1. Subjects completed all the study activities at Week 12 or Week 24 in Study M14 431 or Study M14 433, including the endoscopy, and this information was carried over to the Week 0 visit and served as the reference for all subsequent visits. The duration of Substudy 1 was up to 56 weeks, including a 52-week maintenance period and a 30-day follow-up visit (except for subjects who continued in Substudy 2) from last dose of study drug. The last dose of study drug during this period was taken the day prior to the Week 52 visit. Visits occurred at Week 0, 4, 12, 22, 32, 42 and 52/Premature Discontinuation (PD). All subjects who completed Week 52 visit in Substudy 1 (all cohorts) were eligible to enroll into Substudy 2 (LTE).

Substudy 2 (240-Week LTE)

Substudy 2 enrolled subjects from two sources that were managed as two separate cohorts.

Cohort 4:

Approximately 30 subjects who achieved clinical response in the open-label Extended Treatment Period (Part 3/Cohort 3 of Study M14-431) at Week 24 continued to receive open-label upadacitinib 30 mg QD for 240 weeks.

Cohort 5:

All subjects who completed Substudy 1 were eligible to enroll in this cohort. At Week 0, all subjects continued to receive their originally assigned double-blind treatment (placebo, 15 or 30 mg QD upadacitinib). The treatment assignments were unblinded when the last subject in Substudy 1 completed Week 52, and all subjects receiving upadacitinib continued to receive their treatments until the end of the study. The subjects receiving placebo only received the concomitant CD-related medications, if any. Visits occurred at Week 0, 4, 12, and every 12 weeks thereafter until Week 240/PD. The final visit of Study M14 431 (Week 24) or Substudy 1 (Week 52) was the enrollment visit into Substudy 2. The last dose of study drug during this period was taken the day prior to the Week 240 visit. The duration of Substudy 2 was up to 244 weeks, including a 240-week period and a 30-day follow up visit from last dose of study drug.

For Substudy 1 and 2, subjects used the same subject electronic diary that was dispensed for Study M14-431 or Study M14-433, where they continued to record CD-related symptoms, use of antidiarrheals, and use of medications for endoscopy preparation throughout the study. Subjects were re-instructed to record CD-related symptoms and medications. The diary was reviewed by site personnel with the subject at each visit and for the assessment of the clinical endpoints; the very soft or liquid SF and AP entries from the most recent 7-day period prior to each study visit were used. At each study visit, routine physical examination including evaluation of vital signs, extra-intestinal manifestations, and presence or absence of fistulas; diary review; calculation of Crohn's Disease Activity Index (CDAI) score, average daily SF, and average daily AP score; monitoring of adverse events (AEs); and concomitant medications was performed. The very soft or liquid SF values represented the unweighted daily averages of the corresponding subscores from the CDAI. Additionally, subjects completed quality of life (QoL), CD symptoms and symptoms impact on QoL, and work productivity questionnaires throughout the study.

Subjects underwent a full colonoscopy (ileo-colonoscopy) for evaluation of mucosal inflammation using the Simplified Endoscopic Score for Crohn's disease (SES-CD) at Week 52 (Substudy 1); and at Week 48 and every 48 weeks thereafter (Substudy 2), and all endoscopies were centrally read. In Substudy 1, intestinal biopsies during the endoscopic evaluation were collected for histologic exploratory research at Week 52/PD in approximately 400 subjects who consented to take part in the intestinal biopsy substudy and had collected biopsies in the induction Studies M14-431 and M14-433.

Concomitant CD-Related Medications (Antibiotics, Aminosalicylates, and/or Methotrexate)

In Substudy 1, all subjects receiving CD-related antibiotics could discontinue treatment starting at Week 0 at the discretion of the investigator. All subjects receiving stable dose of CD-related antibiotics (those subjects who did not discontinue), aminosalicylates, or methotrexate (MTX) at Week 0 maintained their concomitant treatments and respective doses through the end of the study. Doses of CD-related antibiotics, aminosalicylates, or MTX were decreased in the event of moderate-to-severe treatment related toxicities. Initiating and/or changing doses of or starting CD-related antibiotics, aminosalicylates, or MTX was prohibited during the study, with the exception of demonstrated inadequate response and need for rescue therapy.

In Substudy 2, doses of CD-related antibiotics, aminosalicylates, or MTX could be changed at the discretion of the investigator and need to be documented in the appropriate electronic case report form.

Concomitant Corticosteroids

In either Substudy 1 or 2, at Week 0, subjects who were taking oral corticosteroid at Baseline of Study M14 431 or M14-433, and initiated but did not completed tapering, continued to have the corticosteroid dose reduced according to a tapering schedule. Initiating locally acting (rectal or suppository) or systemic corticosteroids was prohibited during the maintenance treatment period (Substudy 1), with the exception of demonstrated inadequate response and need for rescue therapy.

Rescue Treatment

Subjects who demonstrated inadequate response (any cohort) and required medical treatment could receive rescue treatment. The criteria for inadequate response were the following:

-   -   Clinical symptoms: Average daily very soft or liquid SF≥4.0         and/or average daily AP score ≥2.0, AND     -   Objective marker of inflammation:         -   High-sensitivity C-reactive protein (hs-CRP)≥upper limit of             normal, and worse than the lowest value assessed during the             study, or         -   Fecal calprotectin (FCP)≥250 μg/g, and worse than the lowest             value assessed in the present study, or         -   SES-CD, excluding the narrowing component, ≥6 (≥4 for             isolated ileal disease), as scored by the site investigator,             assessed at any scheduled study visit with endoscopy or at             an endoscopy performed at an unscheduled visit at the             investigator's discretion.

Substudy 1 (Cohort 1)

Efficacy analysis was based on the intent-to-treat (ITT1) analysis set, which included the first randomized subjects, approximately 501, who had taken at least one dose of study drug in the double blind maintenance period. The comparison between treatment groups on the co-primary efficacy endpoints was performed using the Cochran-Mantel-Haenszel (CMH) test and stratified by prior induction study population 1) Study M14 433, non-bio-IR, 2) Study M14-433 bio-IR, or Study M14-431 Part 1/Part 3, 3) Study M14 431 Part 2, clinical remission per PROs (yes or no), and endoscopic response status (per local read) (yes or no) at Week 12 of Study M14-431 or Study M14-433, or Week 24 for those subjects who received blinded induction treatment with upadacitinib 45 mg QD induction treatment for 12 weeks during the Extended Treatment Period of Study M14-431 (Cohort 1 of Part 3) or Study M14-433 (Cohort 1 of Part 2).

Both of the co-primary efficacy endpoints were tested at two sided significance level of 0.025 for each of the upadacitinib dose groups versus placebo to adjust for multiplicity. A CMH based two-sided 95% confidence interval for the difference between treatment groups was calculated. If average daily very soft or liquid SF or AP score (EU/EMA) or CDAI (US/FDA at Week 52 were missing, the non-responder imputation (NRI) approach was applied for the clinical remission per PROs at Week 52 and clinical remission per CDAI at Week 52 endpoints, respectively. Subjects who discontinued prior to Week 52 for any reason or who initiated rescue therapy were considered as “not achieved” for clinical remission or endoscopic response endpoints.

Secondary efficacy variables were divided into two groups. The first group included ranked secondary endpoints, which were ranked by clinical importance. The second group included all other non-ranked secondary variables.

A multiple testing procedure was used to provide strong control of the type 1 error rate at alpha (α)=0.05 (2-sided) across analyses comparing each upadacitinib dose group to placebo with respect to the co-primary endpoints and ranked secondary endpoints. Specifically, testing utilized a sequence of hypothesis testing for the co-primary endpoints followed by the ranked secondary endpoints, and began with testing each of the co-primary endpoints using α of 0.025 (2-sided) for each dose compared to placebo. If both co-primary endpoints achieved statistical significance within a dose level, continued testing followed a pre-specified weight of a allocation between the single hypothesis within the family, as well as between families of hypotheses across the doses. In general, continuous secondary efficacy variables with repeated measurements were analyzed using a Mixed Effect Repeated Measure (MMRM) model. Continuous secondary efficacy variables which were collected at only one post-baseline visit (such as SES-CD) were analyzed using an Analysis of Covariance (ANCOVA) model. Categorical secondary efficacy variables were analyzed using the CMH test controlling for stratification variables. NRI for missing data was used for categorical secondary endpoints.

Substudy 1 (Cohorts 2 and 3) and Substudy 2

All analyses of efficacy endpoints were performed using the ITT analysis set. Descriptive statistics are provided. Categorical data was summarized by number and percent; and quantitative data was presented by n, mean, standard deviation, minimum value, median, and maximum value.

Pharmacokinetic:

A non-linear mixed-effects modeling approach was used to estimate the population central values and the empirical Bayesian estimates of the individual values of upadacitinib oral clearance and volume of distribution. Additional parameters were estimated if useful in the interpretation of the data. Data from this study could be combined with data from other studies for the population pharmacokinetic analyses.

Safety:

All safety comparisons were performed between treatment groups using the safety analysis set, which consisted of all subjects who received at least one dose of the study drug in the double-blind maintenance period. Treatment-emergent AEs were defined as events that began or worsened either on or after the first dose of the study drug and within 30 days after the last dose of the study drug for subjects who do not participate in Substudy 2 or within 30 days after the last dose of the study drug in Substudy 2. An overview of treatment-emergent AEs, including AEs of special interest, AEs leading to death, AEs leading to premature discontinuation, AEs by Medical Dictionary for Drug Regulatory Activities preferred term and system organ class, AEs by maximum relationship to study drug, and AEs by maximum severity were summarized by number and percentage. Changes from Baseline and from Week 0 in laboratory data were described using statistical characteristics and comparison between-treatment groups will be performed using a one-way analysis of variance. Vital signs and laboratory data were described by statistical characteristics and frequency of abnormal values. In addition, shift tables and listings are provided for abnormal values, whereby the normal range of the analyzing laboratory was used.

Differences Statement

This study was designed to evaluate the efficacy and safety of upadacitinib 15 mg QD and 30 mg QD versus placebo as maintenance therapy in subjects with moderately to severely active CD. The primary differences between Study M14-430 and the parent studies (Studies M14-431 and M14-433) were that this study evaluated lower upadacitinib doses than the 45 mg QD induction dose, and for a long period of time of at least 52 weeks and up to 240 weeks.

Study Objective

Study M14-430 comprised two substudies:

-   -   The objective of Substudy 1 (randomized, double-blind,         placebo-controlled maintenance) was to evaluate the efficacy and         safety of two doses of upadacitinib versus placebo as         maintenance therapy in subjects with moderately to severely         active CD who responded to upadacitinib induction treatment in         Studies M14-431 or M14-433.     -   The objective of Substudy 2 (long-term extension [LTE]) was to         evaluate safety and efficacy of long-term administration of         upadacitinib in subjects with moderately to severely active CD         who participated in the Phase 3 upadacitinib induction and         maintenance studies.         Overall Study Design and Plan

Study M14-430 was a Phase 3, multicenter study to evaluate the efficacy and safety of maintenance and long-term treatment administration of upadacitinib, an orally administered JAK1 inhibitor, in adult subjects with CD. The study was designed to enroll approximately 747 subjects at approximately 400 study centers worldwide to meet scientific and regulatory objectives without enrolling an undue number of subjects in alignment with ethical considerations. The two substudies (Substudy 1 and Substudy 2; FIGS. 52 and 53 , respectively) enrolled concurrently. Baseline was defined as the Baseline Visit of Study M14-431 or Study M14-433 (parent study) and Week 0 was defined as the first study visit in Substudy 1 or Substudy 2.

Substudy 1 (52-Week, Randomized, Double-Blind, Maintenance)

All subjects who achieved clinical response after 12 weeks of induction treatment with upadacitinib or placebo or after blinded treatment in the Extended Treatment Period at Week 24 in Studies M14-431 or M14-433 were eligible to enroll in Substudy 1, and were blinded to treatment assignment. Substudy 1 had three cohorts:

Cohort 1: Approximately 427 subjects who received upadacitinib 45 mg QD induction treatment for 12 weeks in Study M14-431 (from Part 1 or Part 2) or Study M14-433 (Part 1), and approximately 110 subjects who received upadacitinib 45 mg QD induction treatment for 12 weeks during the Extended Treatment Period of Study M14-431 (Cohort 1 of Part 3) or Study M14-433 (Cohort 1 of Part 2) and achieve clinical response were re-randomized in a 1:1:1 ratio to one of the following three treatment groups:

-   -   Group 1: upadacitinib 15 mg QD     -   Group 2: upadacitinib 30 mg QD     -   Group 3: placebo

The randomization was stratified by prior induction population (1) Study M14-433 non-bio-IR, 2) Study M14-433 bio-IR or Study M14-431 Part 1/Part 3, 3) Study M14-431 Part 2, clinical remission (per PROs) status (yes or no), and endoscopic response status (yes or no; based on the local read) at Week 12 or 24 of Study M14-431 or Study M14-433. It was expected that approximately 501 subjects would be re-randomized into Cohort 1 ensuring at least 90% power for simultaneous achievement for the co primary endpoints of clinical remission (per PROs for EU/EMA regulatory purposes and per CDAI for US/FDA regulatory purposes) at Week 52 and endoscopic response at Week 52. The data collected from approximately 501 subjects re-randomized into this cohort was used for the primary efficacy analysis. For this stratification, the endoscopic score of Study M14-431 or Study M14-433 at Baseline from central reader and the endoscopic score at Week 12 or 24 from site local reader was used in order to determine endoscopic response status. The central reader endoscopic score was used for calculating the endoscopic response for the evaluation of the efficacy endpoints.

Cohort 2: Approximately 120 subjects who received double-blind placebo for 12 weeks during Part 1 of Study M14-431 or Study M14-433 and achieved clinical response were assigned by interactive response technology (IRT) to continue to receive blinded placebo.

Cohort 3: Approximately 60 subjects who entered the Extended Treatment Period of Study M14-431 or M14-433 to receive double-blind upadacitinib 30 mg QD for 12 weeks and achieved clinical response at Week 24 were assigned by IRT to continue to receive blinded upadacitinib 30 mg QD.

The last dose of study drug during this period was taken the day prior to the Week 52 visit. The final visit of Study M14-431 or Study M14-433 (Week 12 or Week 24) was the enrollment visit into Substudy 1. Subjects completed all the study activities at Week 12 or Week 24 in Study M14-431 or Study M14-433, including the endoscopy, and this information was carried over to the Week 0 visit and served as the reference for all subsequent visits. The duration of Substudy 1 was up to 56 weeks, including a 52-week maintenance period and a 30-day follow-up visit (except for subjects who continue in Substudy 2) from last dose of study drug. Visits will occur at Week 0, 4, 12, 22, 32, 42 and 52/Premature Discontinuation (PD).

A ±7-day window was permitted around scheduled study visits. At or after Week 4, subjects who met the criteria for inadequate response and required medical treatment (including subjects who met these criteria prior to protocol Amendment 4) could receive rescue therapy. All subjects who completed Week 52 visit in Substudy 1 (all cohorts) were eligible to enroll into Substudy 2 (LTE). Subjects who completed Week 52 were not eligible to enter Substudy 2 until the ileo-colonoscopy at Week 52 had been completed.

Subjects who prematurely discontinued from the study or who did not continue into Substudy 2 had an additional 30-day follow-up visit from the last dose of study drug to collect information about new or ongoing AEs and laboratory assessments. Subjects were discontinued from the study if they withdrew consent or if they were deemed unsuitable to continue for any reason by the investigator. Substudy 2 (240-Week Long-Term Extension)

Substudy 2 enrolled subjects from two sources that were managed as two separate cohorts.

Cohort 4: Approximately 30 subjects who achieved clinical response in the open-label Extended Treatment Period (Part 3/Cohort 3 of Study M14-431) at Week 24 continued to receive open-label upadacitinib 30 mg QD for 240 weeks. At or after Week 4, subjects who met the criteria for inadequate response and required medical treatment could receive rescue treatment.

Cohort 5: All subjects who completed Substudy 1 were eligible to enroll in this cohort. At Week 0, all subjects continued to receive their originally assigned double-blind treatment (placebo, 15 or 30 mg QD upadacitinib). The treatment assignments were unblinded when the last subject in Substudy 1 completed Week 52, and all subjects receiving upadacitinib continued to receive their treatments until the end of the study. The subjects receiving placebo only received the concomitant CD-related medications, if any. During Substudy 2, subjects who met the criteria for inadequate response could receive rescue treatment.

Visits occurred at Week 0, 4, 12, and every 12 weeks thereafter until Week 240/PD. The final visit of Study M14-431 (Week 24) was the enrollment visit of Substudy 2. The day of enrollment of Substudy 2 M14-430 was considered the Week 0 visit of Substudy 2. A ±7-day window was permitted around scheduled study visits. The last dose of study drug during this period was taken the day prior to the Week 240 visit. The duration of Substudy 2 was up to 244 weeks, including a 240-week period and a 30-day follow-up visit from last dose of study drug. All subjects completed all study activities, including the endoscopy during Study M14-431 or Substudy 1 before entering into Substudy 2, and this information was carried over to the Week 0 visit and served as the reference for all subsequent visits and assessments. Subjects who prematurely discontinued from the study had a 30-day follow-up visit from the last dose of study drug to collect information about new or ongoing AEs and laboratory assessments.

For Substudy 1 and 2, subjects used the same subject electronic diary that was dispensed for Study M14-431 or Study M14-433, where they continued to record CD-related symptoms, use of antidiarrheals, and use of medications for endoscopy preparation throughout the study. Subjects were re-instructed to record CD-related symptoms and medications. The diary was reviewed by site personnel with the subject at each visit and for the assessment of the clinical endpoints; the stool frequency (SF) and abdominal pain (AP) entries from the most recent 7-day period prior to each study visit was used.

At each study visit, routine physical examination including evaluation of vital signs, extra-intestinal manifestation (EIMs), presence or absence of fistulas; diary review; calculation of Crohn's Disease Activity Index (CDAI) score, average daily very soft or liquid SF, and average daily AP score; monitoring of AEs; and concomitant medications was performed. The very soft or liquid SF values represented the unweighted daily averages of the corresponding subscores from the CDAI. Additionally, subjects complete dQoL, CD symptoms and symptoms impact on QoL, and work productivity questionnaires throughout the study.

Clinical samples for urinalysis, chemistry and hematology, high-sensitivity C-reactive protein (hs-CRP) were collected. Plasma upadacitinib concentrations was assessed in Substudy 1 only. In addition, stool samples for calprotectin analysis were collected and taken before starting bowel preparations for endoscopy. Subjects underwent a full colonoscopy (ileo-colonoscopy) for evaluation of mucosal inflammation using the Simplified Endoscopic Score for Crohn's disease (SES-CD) at Week 52 (Substudy 1); and at Week 48 and every 48 weeks thereafter (Substudy 2), and all endoscopies were centrally read. In Substudy 1, intestinal biopsies during the endoscopic evaluation were collected for histologic exploratory research at Week 52/PD in approximately 400 subjects who consented to take part in the intestinal biopsy substudy and had collected biopsies in the induction Studies M14-431 and M14-433.

Selection of Study Population

It was anticipated that approximately 747 subjects (approximately 717 subjects in Substudy 1 and approximately 30 subjects in Substudy 2) with CD would be enrolled at approximately 400 sites worldwide. A subject could be enrolled in this study provided that he/she met all of the inclusion criteria and none of the exclusion criteria of this protocol. Substudy 1 enrolled subjects who achieved clinical response (defined as ≥30% decrease in average daily very soft or liquid SF and/or ≥30% decrease in average daily AP score and both not worse than Baseline) at Week 12 of the induction Study M14-431 or Study M14-433 or after the blinded Extended Treatment Period of Study M14-431 or Study M14-433 at Week 24. Substudy 2 enrolled subjects who completed Substudy 1 and subjects from Study M14-431 (Part 3/Cohort 3) who received open-label upadacitinib 30 mg QD in the Extended Treatment Period and achieved clinical response at Week 24.

Any medication or vaccine (including over-the-counter or prescription medicines, vitamins and/or herbal supplements) that was ongoing at the end of Study M14-431 or Study M14-433 and/or that the subject received during the study, was recorded along with the reason for use, date(s) of administration including start and end dates, and dosage information including dose, route and frequency on the appropriate electronic case report form (eCRF).

Concomitant Therapy

Changes in all concomitant medications were assessed at each study visit from Week 0 through Week 52/PD in Substudy 1 and from Week 0 through Week 240/PD in Substudy 2. Any changes were documented in the source documents and captured on the appropriate eCRF page.

Concomitant Crohn's Disease-Related Medications (Antibiotics, Aminosalicylates, and/or Methotrexate)

Substudy 1

All subjects receiving CD-related antibiotics could discontinue treatment starting at Week 0 at the discretion of the investigator. All subjects receiving stable dose of CD-related antibiotics (those subjects who did not discontinue), aminosalicylates, or MTX at Week 0 maintained their concomitant treatments and respective doses through the end of the study. Doses of CD-related antibiotics, aminosalicylates, or MTX could be decreased in the event of moderate-to-severe treatment related toxicities. Initiating and/or changing doses of CD-related antibiotics, aminosalicylates, or MTX was prohibited during the study, with the exception of demonstrated inadequate response and need for rescue therapy.

Substudy 2

In Substudy 2, doses of CD-related antibiotics, aminosalicylates, or MTX could be changed at the discretion of the investigator and were be documented in the appropriate eCRF. Setons were authorized as concomitant therapy in subjects with perianal fistulas and documented in the eCRF under concomitant medications.

Concomitant Corticosteroids

At Week 0 in either Substudy 1 or 2, subjects who were taking oral corticosteroid at Baseline of Study M14-431 or Study M14-433, and initiated but had not completed tapering, continued to have the corticosteroid dose reduced according to the tapering schedule described herein. Initiating locally acting (rectal or suppository) or systemic corticosteroids was prohibited during the maintenance treatment period (Substudy 1), with the exception of demonstrated inadequate response and need for rescue therapy. Use of inhaled or topical (except rectal or suppository) corticosteroids was not restricted. Subjects could not be on both budesonide (for CD disease) and prednisone (or equivalent) simultaneously.

Prohibited Therapy

Biologic Therapies

Therapies including but not limited to the following biologic therapies were prohibited medications during the study: Adalimumab, Etanercept, Infliximab, Abatacept, Anakinra, Rituximab, Natalizumab, Tocilizumab, Golimumab, Certolizumab, Ustekinumab, Belimumab, Secukinumab, Vedolizumab.

The most common strong CYP3A inhibitors include: Boceprevir, Cobicistat, Clarithromycin, Conivaptan, Grapefruit (fruit or juice), Indinavir, Itraconazole, Ketoconazole, Lopinavir/Ritonavir, Mibefradil, Nefazodone, Nelfinavir, Posaconazole, Ritonavir, Saquinavir, Telaprevir, Telithromycin, Troleandomycin, and Voriconazole. The most common strong CYP3A inducers include: Avasimibe, Carbamazepine, Phenytoin, Rifampin (rifampicin), Rifapentine, and St. John's Wort.

Vaccines

Although not mandated by the protocol, vaccines recommended by local guidelines were considered, except for live vaccines, which were NOT allowed during the study or 30 days (longer, if required locally) after the last dose of oral study drug. Examples of live vaccines include, but are not limited to, the following:

-   -   Monovalent live influenza A (H1N1) (intranasal)     -   Seasonal trivalent live influenza (intranasal)     -   Zostavax (herpes zoster, live attenuated)     -   Rotavirus     -   Varicella (chicken pox)     -   Measles-mumps-rubella or measles mumps rubella varicella     -   Oral polio vaccine     -   Smallpox     -   Yellow fever     -   Bacille Calmette-Guérin (BCG)     -   Typhoid (oral)

Examples of common vaccines that are inactivated, toxoid or biosynthetic, include but are not limited to: injectable influenza vaccine, pneumococcal, herpes zoster (Shingrix non-live, recombinant), and pertussis (tetanus-diphtheria-acellular pertussis) vaccines.

Other Medications Prohibited During the Study:

-   -   JAK inhibitors (e.g., tofacitinib [Xeljanz®])     -   Cyclosporine, tacrolimus, thalidomide, mycophenolate mofetil,         AZA, or 6-MP     -   Nonsteroidal anti-inflammatory drugs (NSAIDs) (except topical         NSAIDs and the use of low dose aspirin for cardiovascular         protection)     -   Rectal therapy with any therapeutic enemas or suppositories,         with the exception of those required for endoscopy     -   Any parenteral nutrition and exclusive enteral nutrition     -   Oral or parenteral Traditional Chinese Medicine     -   Investigational drugs     -   Cytapheresis treatment (granulocytapheresis, etc.) (in Japan and         China only)     -   Cannabis         Rescue Therapy

Subjects who demonstrated inadequate response (any cohort) and required medical treatment could receive rescue treatment. These subjects were considered non-responders for the efficacy endpoints from this point forward, but could continue in the study for the safety assessments. The criteria for inadequate response were:

-   -   Clinical symptoms: Average daily very soft or liquid SF≥4.0         and/or average daily AP score ≥2.0, AND     -   Objective marker of inflammation:         -   hs-CRP≥ULN, and worse than the lowest value assessed during             the study or     -   Fecal calprotectin (FCP)≥250 μg/g, and worse than the lowest         value assessed in the present study, or     -   SES-CD, excluding the narrowing component, ≥6 (≥4 for isolated         ileal disease), as scored by the site investigator, assessed at         any scheduled study visit with endoscopy or at an endoscopy         performed at an unscheduled visit at the investigator's         discretion.

Note: At all visits (except Week 4), if the results of hs-CRP and/or fecal calprotectin were unavailable, the results of these from the prior visit could be used for the assessment of inadequate response. In cases in which the endoscopy (scheduled or unscheduled) was being used for eligibility for rescue therapy, the local scoring was used to confirm criteria for inadequate response. The SES-CD from the endoscopy at Week 12 or Week 24 of the induction Studies M14-431 and M14-433 could not be used for determination of criteria for inadequate response. Assessment of inadequate response included consideration by the investigator to rule out symptoms caused by reasons other than CD-related inflammation. At or after Week 4 of Substudy 1 (all cohorts) and during Substudy 2 Cohort 5, subjects who met the criteria for inadequate response and required medical treatment (including those who met the criteria prior to amendment 4), could receive rescue therapy with open label upadacitinib 30 mg QD from that point forward and until the end of the follow up. At or after 4 weeks receiving open-label upadacitinib 30 mg QD (including subjects in Cohort 4), subjects who met the criteria for inadequate response and required medical treatment could initiate or increase the dose, at the investigator's discretion, of any CD-related medication to treat new or worsening of CD symptoms. The allowed CD-related medications were locally acting, oral, or intravenous corticosteroids, aminosalicylates, MTX, or CD-related antibiotics. Antidiarrheal for control of chronic diarrhea was not considered rescue treatment. AZA, 6-MP, cyclosporine, and tacrolimus were prohibited medications during the study and could not be used as a rescue treatment. Changes in CD-related concomitant medications were documented in the appropriated eCRF. After an additional 4 weeks, at the investigator's discretion, subjects could adjust (initiate or increase) the dose of any CD-related medication described above. If the subject continued to meet the criteria for inadequate response after the adjustment of rescue therapy with the allowed CD-related medications at the next study visit, the subject was discontinued from the study. Rescue treatment with allowed CD-related medications was not be withheld even if subject did not meet the criteria for “inadequate response” if in the opinion of the investigator, failure to prescribe them would have compromise the subject's safety. Subjects could also be discontinued at any time based on the investigator's medical assessment. For subjects receiving corticosteroids as a rescue treatment, the investigator was encouraged to initiate tapering based on the subject clinical response status.

Clinical Laboratory Tests

Samples were obtained for the clinical laboratory tests listed in Table 44 and at specified visits. Unscheduled clinical labs could be obtained at any time during the study if deemed appropriate per investigator's discretion. A certified central laboratory was utilized to process and provided results for the clinical laboratory tests. A laboratory test value that required a subject to be discontinued from study drug or required a subject to receive treatment was recorded as an AE. Other laboratory abnormalities, including those which met the toxicity management criteria outlined herein, were recorded as AEs at the discretion of the investigator.

Other Laboratory Assessments High-Sensitivity C-Reactive Protein (hs-CRP)

Blood samples for hs-CRP were obtained as specified. For both Substudy 1 and 2, at or after Week 4, the hs-CRP results were blinded to the sponsor, investigator, study site personnel and the subject. The hs-CRP test was performed by the central lab.

Urinalysis

Dipstick urinalysis (macroscopic analysis) was completed by the central laboratory at all required visits. A microscopic urinalysis was only performed by the central laboratory if the dipstick urinalysis results were abnormal, where abnormal was defined as leukocytes, nitrite, ketone, protein, blood, or glucose value of greater than a trace.

Lymphocyte Subsets

Blood samples were collected at specified visits during Substudy 1 only to assess lymphocyte subsets: T (cluster of differentiation [CD]4+ and CD8+) cells, B (CD19+) cells, NK cells, and NKT cells.

Outcomes and Questionnaires

The following outcomes and questionnaires were completed at the appropriate time points:

-   -   Inflammatory Bowel Disease Questionnaire (IBDQ)     -   Work Productivity and Activity Impairment Questionnaire         (WPAI)-CD     -   Crohn's Symptoms Severity (CSS) Questionnaire     -   Short Form-36 (SF-36)     -   European Quality of Life 5 Dimensions 5 Levels (EQ-5D-5L)     -   Functional Assessment of Chronic Illness Therapy-Fatigue         (FACIT-F)     -   Patient Global Impression of Change (PGIC)     -   Patient Global Impression of Severity (PGI-S)     -   Bristol Stool Chart         Study Drug Dispensing/Administration

Study drug was dispensed to subjects at Week 0 and at each visit through Week 228, with the exception of Week 4. Study drug was to be taken orally QD beginning at Week 0 and to be taken at approximately the same time each day.

Crohn's Disease Activity Index (CDAI)

Average daily very soft or liquid SF, average daily AP score, and well-being were calculated from the subject diary. During Week 0 subjects were re-instructed on how to calculate the number of very soft and liquid stools, including a visual depiction based on the Bristol Stool Chart. Physical exam and appropriate laboratory values were calculated at all study visits, except the 30-day follow-up visit. The CDAI scores were calculated using a hematocrit (Hct) value from the same visit laboratory work. The final CDAI for each visit was calculated once the Hct value was received from the central lab.

Endoscopy

An endoscopy (ileocolonoscopy) will be performed. For subjects in Substudy 1, it is expected that all subjects who remain in the study through at least Week 8 will have a Week 52/PD endoscopy.

Corticosteroid Taper

At Week 0, subjects who were taking corticosteroid at Baseline of Study M14-431 or Study M14-433, have initiated but had not completed tapering, continued to have the corticosteroid dose reduced according to a tapering schedule. If a subject was unable to tolerate the corticosteroid taper, the subject could have the taper stopped or their corticosteroid dose increased, per the investigator's discretion, up to the dose used at Baseline of Study M14-431 or Study M14-433. If the subject experienced loss of adequate response during or after the corticosteroid taper and fulfilled the criteria for inadequate response and needed medical treatment, the rescue treatment may have been applied. With the exception of rescue therapy due to demonstrated inadequate response, initiating locally acting (rectal or suppository) or systemic corticosteroids was prohibited during the maintenance treatment period (Substudy 1), and was considered a protocol deviation.

The IRT assigned a randomization number that encoded the subject's treatment group assignment according to the randomization schedule generated by the Statistics Department at AbbVie. IRT provided the appropriate medication kit number(s) to dispense to each subject. In Cohort 1, subjects (approximately n=537) were randomized in a 1:1:1 ratio to upadacitinib 15 mg QD, upadacitinib 30 mg QD, or matching placebo for 52 weeks (FIG. 52 ). The randomization wad stratified by prior induction study population (1) Study M14-433 non-bio-IR, 2) Study M14-433 bio-IR or Study M14-431 Part 1/Part 3, 3) Study M14-431 Part 2), clinical remission per PROs status (yes or no), and endoscopic response status (yes or no; based on the local read) at Week 12 or 24 of Study M14-431 or Study M14-433. In Cohorts 2 and 3, subjects were assigned by IRT to continue to receive blinded placebo or blinded upadacitinib, respectively, until Week 52.

Substudy 2

In Cohort 4, subjects continued to receive open-label upadacitinib 30 mg QD for 240 weeks.

In Cohort 5, all subjects receiving upadacitinib continued to receive their originally assigned double-blind treatment (upadacitinib 30 mg QD, or upadacitinib 15 mg QD). The subjects receiving placebo only received the concomitant CD-related medications, if any. The treatment assignments were unblinded when the last subject in Substudy 1 completed Week 52.

Selection and Timing of Dose for Each Subject

On dosing days that occurred on study visit days, subjects followed the regular dosing schedule. Each subject's dosing schedule was closely monitored by the site at each study visit. This ensured that all subjects enrolled into the study maintained their original dosing schedule beginning with the first dose of study drug (Week 0/Day 1). If a subject forgot to take upadacitinib (or matching placebo) dose at their regularly scheduled dosing time, they took the forgotten dose as soon as they remembered the dose was missed as long as it was at least 10 hours before their next scheduled dose. If a subject only remembered the missed dose within 10 hours before next scheduled dose, the subject could skip the missed dose and take the next dose at the scheduled time. For elective and emergency surgeries, the following rules applied:

-   -   If the subject underwent emergency surgery, the study drug was         interrupted at the time of the surgery. After emergency surgery,         reintroduction of study drug was allowed once the physician had         examined the surgical site and determined that it had healed and         there was no sign of infection.     -   Elective surgery was not allowed during the study until the         primary endpoint had been assessed. If the subject underwent         elective surgery, the study drug was interrupted 1 week prior to         the planned surgery. Reintroduction of study drug was allowed         once the physician had examined the surgical site and determined         that it had healed and there was no sign of infection.         Discussion of Study Design and Choice of Control Groups

This study included two substudies:

-   -   Substudy 1 was a 52-week, randomized, double-blind, maintenance         substudy that includes three cohorts. Cohort 1 evaluated the         efficacy and safety of two doses of upadacitinib versus placebo         as maintenance therapy in subjects with moderately to severely         active CD who responded to upadacitinib induction treatment in         Study M14-431 or Study M14-433. A comparative study utilizing         placebo provided an unbiased assessment of the efficacy and         safety profile of upadacitinib during maintenance treatment in         subjects who responded to the induction treatment. Cohorts 2 and         3 enrolled subjects who achieved clinical response to placebo or         from the Extended Treatment Period with upadacitinib,         respectively. These two cohorts maintained the treatment         received in the induction studies in a blinded manner and did         not have a control group.     -   The purpose of Substudy 2 was to evaluate the safety and         efficacy of long-term administration of upadacitinib in subjects         who participated in the Phase 3 upadacitinib induction and         maintenance studies. During the follow up, subjects receiving         placebo were used as a reference group, for the descriptive         analyses of the safety and efficacy.         Selection of Doses in the Study

This study evaluated two maintenance doses of upadacitinib at 15 mg and 30 mg QD. The selection of these doses was informed by the analysis of the 16-week safety, efficacy, and exposure-response data of Study M13-740, a Phase 2 study in subjects with moderately to severely active CD that explored five induction doses of upadacitinib using the immediate-release formulation (3, 6, 12, or 24 mg BID or 24 mg QD) versus placebo. In addition, all the currently available PK, pharmacodynamic, safety, and efficacy data from upadacitinib studies were used to support the selection of these doses. The induction phase results from Study M13-740 demonstrated the clinical and endoscopic efficacy of upadacitinib compared to placebo with doses of 6 mg BID and higher. The doses of 15 mg QD and 30 mg QD using the once-daily formulation provide equivalent daily area under the concentration-time curve (AUC) and comparable minimum plasma concentration (C_(min)) and maximum plasma concentration (Cmax) to 6 mg BID and 12 mg BID, respectively, using the immediate-release formulation. Following induction with 45 mg QD, doses of 15 mg QD and 30 mg QD are expected to maintain clinical and endoscopic response while having better long-term safety profile compared to higher doses. Doses of 15 mg QD and 30 mg QD for up to 240 weeks were expected to be efficacious with an acceptable safety profile.

Adverse Events of Special Interest

The following AEs of special interest will be monitored during the study: Serious infections; Opportunistic infections; Herpes zoster; Active TB; Malignancy (all types); Adjudicated gastrointestinal perforations; Adjudicated cardiovascular events (e.g., major adverse cardiac event [MACE]); Anemia; Neutropenia; Lymphopenia; Renal dysfunction; Hepatic disorder; Elevated CPK; Adjudicated embolic and thrombotic events (non-cardiac, non-central nervous system [CNS]).

Toxicity Management

The toxicity management of the AEs including AEs of special interest consisted of safety monitoring (review of AEs on an ongoing basis, and periodical/ad hoc review of safety issues by a safety data monitoring committee), interruption of study drug dosing with appropriate clinical management if applicable, and discontinuation of the subjects from study drug. The management of specific AEs and laboratory parameters is described below. For subjects who discontinued study drug but continued study participation and were on standard of care therapies, these toxicity management requirements did not apply (including alerts from the central lab) and any intolerability to standard of care therapies was managed by the prescribing physician.

Serious Infections

Subjects were closely monitored for the development of signs and symptoms of infection during and after treatment with study drug. Study drug was interrupted if a subject developed a serious infection. A subject who developed a new infection during treatment with study drug underwent prompt diagnostic testing appropriate for an immunocompromised subject. As appropriate, antimicrobial therapy was initiated, and the subject closely monitored. Study drug was resumed once the infection had been successfully treated. Subjects who developed active TB were discontinued from study drug.

Herpes Zoster:

If a subject developed herpes zoster, temporarily interrupting study drug until the episode resolves was considered.

Gastrointestinal Perforation:

Subjects presenting with the onset of signs or symptoms of a gastrointestinal perforation were evaluated promptly for early diagnosis and treatment. If the diagnosis of gastrointestinal perforation was confirmed (other than appendicitis or mechanical injury), the subject was discontinued from study drug.

Cardiovascular Events (MACE):

Subjects presenting with potential cardiovascular events were appropriately assessed and carefully monitored. These events were reviewed and adjudicated by an independent CAC in a blinded manner.

Thrombosis Events:

Subjects who developed symptoms of thrombosis were promptly evaluated and treated appropriately. If the diagnosis of deep vein thrombosis, pulmonary embolus, nonneurologic, non-cardiac arterial thrombosis was confirmed, the subject was discontinued from the study drug.

COVID-19:

Study drug in subjects with a confirmed diagnosis of COVID-19 was interrupted. Interruption of study drug in subjects with signs and/or symptoms and suspicion of COVID-19 was considered. Malignancy:

Subjects who developed malignancy or high-grade colonic dysplasia, other than NMSC or carcinoma in situ of the cervix were discontinued from study drug. Periodic skin examination was recommended for subjects who were at increased risk for skin cancer.

ECG Abnormality:

Subjects were discontinued from study drug for an ECG change considered clinically significant and with reasonable possibility of relationship to study drug, OR a confirmed absolute QTcF value >500 msec.

Management of Select Laboratory Abnormalities:

For any given laboratory abnormality, the investigator assessed the subject, applied the standard of care for medical evaluation and treatment followed any local guidelines. Specific toxicity management guidelines for abnormal laboratory values are described in Table 45. All abnormal laboratory tests that were considered clinically significant by the investigator were followed to satisfactory resolution. If a repeat test was required per Table 45, the repeat testing occurred as soon as possible.

TABLE 45 Specific Toxicity Management Guidelines for Abnormal Laboratory Values Laboratory Parameter Toxicity Management Guideline Hemoglobin If hemoglobin <8 g/dL interrupt study drug dosing and confirm by repeat testing with a new sample. If hemoglobin decreases ≥3.0 g/dL from Week 0 without an alternative etiology, interrupt study drug dosing and confirm by repeat testing with new sample. If hemoglobin decreases ≥3.0 g/dL from Week 0 and an alternative etiology is known, or the hemoglobin value remains in the normal reference range, the subject may remain on study drug at the investigator's discretion. If confirmed, continue to withhold study drug until hemoglobin value returns to normal reference range or its Week 0 value. ANC If confirmed <1000/μL by repeat testing with new sample, interrupt study drug dosing until ANC value returns to normal reference range or its Week 0 value. Interrupt study drug if confirmed <500/μL by repeat testing with new sample. If value returns to normal reference range or its Baseline value, restarting study drug is allowed if there is an alternative etiology identified; documentation should include reason rechallenge is expected to be safe for the subject. Study drug should be discontinued if no alternative etiology can be found. ALC If confirmed <500/μL by repeat testing with new sample, interrupt study drug dosing until ALC returns to normal reference range or its Week 0 value. Total WBC If confirmed <2000/μL by repeat testing count with new sample, interrupt study drug dosing until WBC count returns to normal reference range or its Week 0 value. Platelet count If confirmed <50,000/μL by repeat testing with new sample, interrupt study drug dosing until platelet count returns to normal reference range or its Week 0 value AST or ALT Interrupt study drug if confirmed ALT or AST >3 × ULN by repeat testing with new sample and either a total bilirubin >2 × ULN or an international normalized ratio (INR) >1.5. A separate blood sample for INR testing will be needed to measure INR at the time of repeat testing for ALT or AST. A repeat test of INR is not needed for determination if above toxicity management criteria are met. Interrupt study drug if confirmed ALT or AST >3 × ULN by repeat testing with new sample along with new appearance of fatigue, nausea, vomiting, right upper quadrant pain or tenderness, fever, rash, and/or eosinophilia (>5% increase from Baseline). Interrupt study drug if confirmed ALT or AST >8 × ULN by repeat testing with new sample. Interrupt study drug if confirmed ALT or AST >5 × ULN by repeat testing with new sample for more than 2 weeks. For subjects with positive HBc Ab (irrespective of HBs Ab status) and negative HBV DNA at screening who develop the following laboratory findings should have HBV DNA by PCR testing should be performed within 1 week (based on initial elevated value): ALT >5 × ULN OR ALT/AST >3 × ULN, if an alternative cause is not readily identified A separate blood sample for HBV DNA by PCR testing will be needed at the time of repeat testing for ALT or AST. A positive result for HBV DNA PCR testing in these subjects will require immediate interruption of study drug and a hepatologist consultation should occur within 1 week for recommendation regarding subsequent treatment. Subjects who meet any of the above criteria should be evaluated for an alternative etiology of the ALT or AST elevation and managed as medically appropriate. The investigator should contact the AbbVie TA MD to discuss the management of a subject when an alternative etiology has been determined. The alternative etiology should be documented appropriately in the eCRF; study drug should be discontinued if no alternative etiology can be found and ALT or AST elevations persist. If ALT or AST values return to the normal reference range or its Baseline value, study drug may be restarted. If restarting study drug, documentation should include reason rechallenge is expected to be safe. Serum If serum creatinine is >1.5 × the Week 0 creatinine value and >ULN, repeat the test for serum creatinine (with subject in a euvolemic state) to confirm the results. If the results of the repeat testing still meet this criterion then interrupt study drug and restart study drug once serum creatinine returns to ≤1.5 × Week 0 value and ≤ULN. CPK If any confirmed CPK value ≥4 × ULN (if symptomatic or asymptomatic). If confirmed CPK ≥4 × ULN accompanied by symptoms suggestive of myositis or rhabdomyolysis, interrupt study drug Datasets for Analysis Intent-to-Treat Analysis Set

The intent-to-treat analysis set (ITT1) for Substudy 1 Cohort 1 was to include the first randomized subjects, approximately 501, who received at least one dose of study drug in the double-blind maintenance period. The intent-to-treat (ITT) analysis set for Substudy 1 Cohort 2 and Cohort 3 was to include all enrolled subjects who received at least one dose of study drug in the double-blind maintenance period. The ITT and ITT1 subjects were to be analyzed as randomized. The ITT1 set was to be the primary population for efficacy analysis in Substudy 1. The ITT analysis set for Substudy 2 was to include all subjects who received at least one dose of study drug in the LTE period. The ITT set was to be the primary population for efficacy analysis in Substudy 2.

Safety Analysis Set

The safety analysis set was to consist of all subjects who received at least one dose of the study drug. The safety analysis set was to be analyzed as treated, according to treatment the subject actually received. The safety analysis set was used for safety analysis.

Substudy 1: Was to include all subjects who received at least one dose of study drug in the double-blind maintenance period of the study (including nonrandomized subjects).

Substudy 2: Was to include all subjects who received at least one dose of study drug in the LTE phase of the study.

Randomization Methods

Approximately 427 subjects who received upadacitinib 45 mg QD induction treatment for 12 weeks in Study M14-431 (from Part 1 or Part 2) or Study M14-433 (Part 1), and approximately 110 subjects who received upadacitinib 45 mg QD induction treatment for 12 weeks during the Extended Treatment Period of Study M14-431 (Cohort 1 of Part 3) or Study M14-433 (Cohort 1 of Part 2) and achieved clinical response were to be re-randomized in a 1:1:1 ratio to one of the following three treatment groups:

-   -   Group 1: Upadacitinib 15 mg     -   Group 2: Upadacitinib 30 mg     -   Group 3: Placebo

The randomization was to be stratified by prior induction study population (1) Study M14-433 non-bio-IR, 2) Study M14-433 bio-IR or Study M14-431 Part 1/Part 3, 3) Study M14-431 Part 2), clinical remission per PROs status (yes or no), and endoscopic response status (yes or no; based on the local read) at Week 12 or 24 of Study M14-431 or Study M14-433. Subjects enrolling in Cohorts 2 and 3 of this study were assigned placebo and upadacitinib 30 mg QD, respectively, in a blinded fashion. Subjects enrolled into Cohort 4 in an open-label manner. Subjects enrolling into Cohort 5 were assigned placebo or upadacitinib 30 mg QD or upadacitinib 15 mg QD in a blinded fashion, according to the randomized treatment received in Substudy 1.

Patient Reported Outcomes Descriptions

IBDQ—Inflammatory Bowel Disease Questionnaire

The IBDQ is a disease-specific instrument composed of 32 Likert-scaled items. The total score ranges from 32 to 224 using the 7-point response options, with higher scores indicating better health-related quality of life. The IBDQ scale contains 4 component subscales: bowel symptoms, systemic symptoms, emotional function, and social function. Each subscale can be computed with total scores ranging from 10-70, 5 to 35, 12 to 84, and 5 to 35, respectively.

WPAI-CD—Work Productivity and Activity Impairment Questionnaire—Crohn's Disease

The Work Productivity and Activity Index assesses the impact of the condition on work productivity losses and impairment in daily activity. WPAI has six items covering four domains: Absenteeism (work time missed), measured as the number of hours missed from work in the past 7 days due to condition related problems. Scores are expressed as impairment percentages, adjusting for hours actually worked according to the WPAI scoring algorithm; Presenteeism (impairment at work/reduced on-the-job effectiveness), measured as the impact of the condition on productivity while at work (i.e., reduced amount or kind of work, or not as focused as usual). Responses are recorded on a 0-10 Likert scale (where, 0=no effect of CD on work and 10=severe impact of CD while at work); productivity loss (overall work impairment), measured as the sum of hours missed due to condition i.e., absenteeism and number of hours worked with impairment i.e., product of number of hours worked and presenteeism; and activity impairment (i.e., activities other than paid work like work around house, cleaning, shopping, traveling, studying), recorded and scored in same way as presenteeism. Higher numbers indicate greater impairment and less productivity.

CSS—Crohn's Symptoms Severity Questionnaire

The CSS questionnaire is a 14-item assessment of both GI and non-GI CD symptoms using a 7-day recall period. The 14 items assess the frequency or intensity of each individual symptom by utilizing a 5-point Likert-type scale. An assessment of an individual items frequency and intensity is measured as follows:

-   -   Frequency: 1=Never, 2=Rarely, 3=Sometimes; 4=Often, 5=Always     -   Intensity: 1=Not at all, 2=A little bit; 3=Somewhat; 4=Quite a         bit; 5=Very much         An overall symptom score is calculated by combining ratings from         the 14 individual items (possible scores range from 14 to 70)         with higher scores indicating greater symptom frequency or         intensity.         SF-36—Short Form 36

The SF-36 questionnaire is a self-administered multi-domain scale with 36 items. Eight subscales cover a range of functioning: physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health. The scoring yields a physical component score, a mental component summary score, and subscale scores. Higher scores represent better outcomes. The concepts measured by the SF-36 are not specific to any age, disease, or treatment group, allowing comparison of relative burden of different diseases and the benefit of different treatments.

EQ-5D—European Quality of Life 5 Dimensions

The EQ-5D-5L is a standardized non-disease specific instrument for describing and valuing health-related quality of life. The EQ-5D consists of 5 dimensions: mobility, self care, usual activity, pain/discomfort, and anxiety/depression. Each dimension has 5 levels: no problem, slight problem, moderate problem, severe problem or unable to do the activity. It also contains a Visual Analogue Scale (VAS). Subjects are asked to indicate the level that describes their current level of function or experience for each dimension. As a measure of health status, it provides a descriptive profile and can be used to generate a single index value for health status, where full health is equal to 1 and death is equal to 0. The VAS records the subject's assessment of his/her own health along a vertical 20 cm line, which has health state scores between 0 and 100.

FACIT-F—Functional Assessment of Chronic Illness Therapy-Fatigue

The FACIT system is a collection of quality of life (QoL) questionnaires targeted to the management of cancer and other chronic illnesses. The FACIT fatigue (FACIT-F) questionnaire was developed to assess fatigue associated with anemia. It consists of 13 fatigue-related questions. The responses to the 13 items on the FACIT fatigue questionnaire are each measured on a 4-point Likert scale. The responses to the answers are the following: (i) not at all: 0 points; (ii) a little bit: 1 point; (iii) somewhat: 2 points; (iv) quite a bit: 3 points; (v) very much: 4 points. Thus, the total score ranges from 0 to 52. High scores represent less fatigue.

PGIC—Patient Global Impression of Change

The PGIC is a self-administered instrument that assesses change in the overall symptoms due to Crohn's disease. The PGIC is one item in which subjects are asked to rate overall improvement since start of the treatment. Subjects rate their change as “Very much improved,” “Much improved,” “Minimally improved,” “No change,” “Minimally worse,” “Much worse” and “Very much worse.”

PGI-S—Patient Global Impression of Severity

The PGI-S is a self-administered instrument that assesses the severity of the overall symptoms due to Crohn's disease. The PGI-S is one item in which subjects are asked to rate overall severity of symptoms over the past week. Subjects rate their change as “Absent,” “Minimal,” “Mild,” “Moderate,” “Moderately severe,” “Severe” and “Very severe.”

Corticosteroid Taper Schedule

At Week 0, all subjects who were taking steroids at Baseline of Study M14-431 or Study M14-433 and had not completed the corticosteroid taper, continued the mandatory taper schedule outlined in FIGS. 54 and 55 .

Results

Study M14-430 was a Phase 3 maintenance and long-term extension (LTE) study to evaluate the maintenance and long-term safety and efficacy of upadacitinib (UPA) in subjects with moderately to severely active Crohn's disease (CD) who have completed induction studies M14-431 or M14-433. At Week 0, all subjects who achieved clinical response (defined as ≥30% decrease in average daily very soft or liquid SF and/or ≥30% decrease in average daily AP score, with both SF and AP not worse than Baseline) at the end of the Induction Studies M14-431 or M14-433 were to enroll in Sub-study 1 and to receive study drug in a blinded fashion.

This study contained two sub-studies: Sub-study 1 included a 52-week Maintenance Period, and Sub-study 2 included a 240-week LTE Period. Sub-study 1 contained 3 cohorts.

Cohort 1: Subjects who received the 12-week induction treatment with UPA 45 mg and achieved clinical response in studies M14-431 or M14-433 were randomized to receive double-blind UPA 30 mg, UPA 15 mg, or placebo (PBO) in a 1:1:1 ratio. The randomization was stratified by bio-IR and non-bio-IR status in the induction studies, as well as the clinical remission (per PROs) and endoscopic response status at the entry of M14-430 Sub-study 1. According to the protocol, all primary and secondary efficacy endpoints were analyzed among the ITT1 Population, which included the first approximately 501 subjects* who were randomized and received at least one dose of study drug. The actual number of subjects included in the ITT1 Population was 502,

Cohort 2: Subjects who received the 12-week induction treatment with PBO and achieved clinical response in studies M14-431 or M14-433 continued to receive double-blind PBO.

Cohort 3: Subjects who initially did not achieve clinical response after the 12-week induction treatment with UPA 45 mg, received the 12-week extended treatment with UPA 30 mg and achieved clinical response in studies M14-431 or M14-433, continued to receive double-blind UPA 30 mg.

Starting from Week 4, subjects who met the criteria for inadequate response had the option to receive rescue therapy with open label (OL) UPA 30 mg QD from that point forward. Subjects would be considered as non-responders after being rescued.

A total of 674 subjects were randomized (223 in PBO, 221 in UPA 15 mg, and 230 in UPA 30 mg) in Cohort 1 of Sub-study 1, 673 received at least one dose of study drug. Among these subjects, 502 were randomized on or prior to Mar. 29, 2021; and were included in the Primary Analysis for efficacy (i.e., the ITT1 Population).

In the ITT1 Population, a total of 381 (75.9%) subjects completed the study drug in Sub-study 1 (Table 46). Among these, higher proportion of subjects from the PBO group received the rescue treatment with open-label UPA 30 mg. Baseline demographics and disease characteristics were generally balanced between treatment groups.

Efficacy

The study has different sets of co-primary endpoints and key secondary endpoints for EU/EMA and US/FDA regulatory purposes. Under either strategy, the overall type-I error rate is strongly controlled with a 2-sided alpha level of 0.05. Co-primary endpoints were achieved for both EU/EMA (Table 47) and US/FDA (Table 48) regulatory purposes, demonstrating the superiority of both UPA 30 mg vs. PBO and UPA 15 mg vs. PBO, with p<0.0001. Consistent efficacy results for co-primary endpoints were observed among subgroups of non-bio-IR/bio-IR subjects, as well as in the sensitivity analyses. In addition, 10 out of 11 key secondary endpoints for UPA 30 mg vs. PBO and 8 out of 11 for UPA 15 mg vs. PBO were achieved, according to the pre-defined strategy for overall type-I error control.

The proportion of subjects achieving steroid-free clinical remission per PRO and CDAI among all subjects is provided in FIGS. 60C and 60D, respectively. Referring to FIGS. 60 c and 60D, steroid-free clinical remission was achieved at Week 52 among all subjects per both PRO and CDAI.

The proportion of subjects achieving endoscopic response at Week 52 with for placebo, upadacitinib 15 mg, and upadacitinib 30 mg is provided in FIG. 61A. Endoscopic response was defined as a decrease in SES-CD>50% from baseline (or for subjects with isolated ileal disease and a baseline SES-CD of 4, at least a 2-point reduction from baseline), scored by central reader.

The proportion of subjects achieving endoscopic remission at Week 52 with for placebo, upadacitinib 15 mg, and upadacitinib 30 mg is provided in FIG. 61B. Endoscopic remission was defined as SES-CD≤4 and at least a 2-point reduction versus baseline and no subscore greater than 1 in any individual variable, as scored by central reader.

The proportion of subjects achieving maintenance of clinical remission per PROs and CDAI for placebo, upadacitinib 15 mg, and upadacitinib 30 mg is provided in FIG. 62A, defined as clinical remission (per PROs or CDAI) at Week 52 among subjects in Clinical Remission at Week 0.

The proportion of subjects achieving deep remission per PROs and CDAI for placebo, upadacitinib 15 mg, and upadacitinib 30 mg is provided in FIG. 62B, defined as achievement of clinical remission per PROs or CDAI and Endoscopic Remission at Week 52. 

The invention claimed is:
 1. A method of treating Crohn's disease in an adult patient having moderately to severely active Crohn's disease to achieve clinical remission, the method comprising: (a) orally administering to the patient an induction dose of 45 mg of upadacitinib once daily for 12 weeks; and (b) orally administering to the patient, after the last induction dose of 45 mg of upadacitinib, a maintenance dose of 15 mg of upadacitinib once daily, wherein the method achieves clinical remission of the Crohn's disease in the patient.
 2. The method of claim 1, wherein the method achieves induction of clinical remission per Crohn's Disease Activity Index (CDAI) at 12 weeks after the administration of the initial induction dose of 45 mg of upadacitinib.
 3. The method of claim 1, wherein the method achieves maintenance of clinical remission per Crohn's Disease Activity Index (CDAI) at 52 weeks after administration of the initial maintenance dose of 15 mg of upadacitinib.
 4. The method of claim 1, wherein prior to receiving the initial induction dose the adult patient had an inadequate response or intolerance to a previous treatment with an anti-TNF agent.
